To summarize
Foss tube - 160gr
Normal tube - 203gr
Normal tube with Slime - 316gr
Foss has it's good points, Slime has it's good points. Foss + Slime = winnar?
Foss + Slime - 279gr

While that tube is unquestionably awesome, I think there's still plenty of potential for puncture flats in real world scenarios. If the puncturing object doesn't stay inserted in the tube (let's say it's a nail big enough to get knocked out by the rotation of the wheel), you're still going to lose air.

Does slime even work in "road" tubes?
A certain volume of air is going to escape at the time you get the puncture, before the slime sets. While this volume may not be too significant compared to the overall air volume in, say a f'n mtb tire, or otherwise high-f'n-volume tire, the amount of air that a 25c @ 90psi f'n setup would lose might be a different story.
But please, tell me I'm f'n wrong. I haven't f'n used slime since my last f'n mtb (10 years ago), and I'm totally making this up as I f'n go.
It sure does, but you probably want Slime Lite: 19-25 & 28-32.
I do not understand the overwhelmingly negative reviews on REI. I have 5 of the 28-32 slime lite tubes running on my bikes and I haven't had a single problem (or flat tire) once I installed them. And somewhere I have photo proof of them sealing a puncture, I only noticed slime had prevented the flat when I was switching out road tires for cross tires.
Those tubes + slime seem like a win. Or just, you know, slime. As Jon said, really, you're just going to leave a pokey thing in there?

When is the last time anyone had a nail/tack/screw puncture? Were you able to ride with the object still in your tire? The few times i've been on rides and seen these types of punctures the nail had to be removed inroder to keep riding. In addition to the tube dammage the tire was also pretty compromised.
The most punctures I can recall having have come from glass shards, in the rain, at night. This would point me towards slime I guess. I think I would only use that on a dedicated commuter bike though.

The nails and thumbtacks are demo standins for goatheads, which can def be ridden around on if you've got something to prevent the air loss. We don't have those around here.
What we do have is a lot of pinch flats, and these tubes do prevent that.

that requires a pretty special definition of good, where the tires can approach a kilo apiece and have enough rolling resistance to bring you to a halt on a shallow downhill

Yeah I was just speaking to my own experiences and asking for other's direct experiences.
Since I have an escalating arms race for tire air volume between my bikes I haven't had a flat I have identified as a pinch flat in a long time. Thinking back over 10 years of riding glass was still my top failure mode and so I'm curious how a FOSS would respond to that. I'm picturing it may last longer if glass is embedded in the tire but may eventually cause a hole but since it is a less uniform shape than a nail or goathead I don't know how well it would seal around it.
(~5) glass shards
(3) black berry thorns, 2 were slow leaks
(2) tube/valve rot/separation
(1) steel shaving/sliver
(1) valve failure
(1) upholstery tack
(1) sharp sliver of shale type rock
(1) Tire blew off rim when MTBing
I had an inch long cactus thorn in my tire on Monday. It was a slow leak (I probably rode 10 miles from where I picked it up).

I stand corrected, good meaning not worn the fuck out. I've had cheap tires and expensive tires and they all are flat free until that one week when I get 4 fucking flats in a row. Never have pinch flatted.I'm waiting for the day when it happens

Yeah. Multiple flats in close proximity (not the same flat repeated by an unfound object) point towards the tire being the culprit and this time to pony up for a new tire or two.
I've come to accept the occasional flat though. Problem is when my number does come up is can really be a whopper though. I do my best to keep my tires inflated and ride away from debris when I can but sometimes you just can't win.
I had a terrible flat this fall. Hit a big bump in the rain at night, flatted shortly there after. Thought it was a pinch flat, patched the tube. Inflated rode, flatted again. Found glass that I had missed the first time. Removed it, no more patches or glue or something. Jimmy had a spare tube, installed, pumped up, valve blew off when i removed the pump. WTF?! Luckily Jimmy had a 26" tube that somehow we stretch over a 700c tire and got inflated. I limped home on that.

I am generally with Eric. I prefer getting good tires and then having to deal with less flats. I have had really good luck with Schwalbe marathon tires. I have been getting 2000+ miles on a tube. I had one in Africa that I think went over 4000 miles before the tube actually wore thin and popped. The tire had protected it from acacia thorns, glass, nails and hot desert sand. On my city bike I have done 3000 miles with just one flat.
I have also heard good things about Continental tires, but I don't have any experience with them.
I used a free pair of Michellin cyclocross tires for a while. I ditched them because I was getting a flat every second or third ride. My "free" tires ended up costing me a bunch of money in tubes. So you really aren't doing yourself a favor with cheap tires.
I don't think it matters what tube you have, or if you have crap inside the tube, if your tires aren't protecting them. No tire is ever going to be 100% effective at preventing flats, but that is where I seem to get the most flat prevention. If you get tubes that also prevent flats, it won't hurt anything. The money might be spent better elsewhere. What is the cost breakdown between the Foss and regular tubes?
The last flat I had with the Michellins, I rode over a staple (damn political signs). That one I noticed because the staple was stuck in the tire and clicking as I was going down the road. So I guess the Foss tubes would have helped there. By the time I stopped the tube was completely out of air. I had to carry my bike a mile home, in the rain...
If the Foss tubes help to slow the leak, that could be a big benefit. Depending on the conditions I often perfer pumping up a slow leak to limp home rather than repairing a tube, say in the rain at night.

Sorry to derail (pun intended) this thread, but Matt's post reminds me of a question I've been meaning to ask. It's getting close to time to replace the tires on my Miyata, which currently has, I think, 700x35 Schwalbe Marathon Plus (with the reflective sidewalls).
I've been happy with these tires, mostly, but among the 425 different varieties of Schwalbe Marathons, which is the .83-approved choice? I seem to remember this conversation coming up before, but can't find the thread.
I got the plus 28's with the reflective sidewall and I beat the shit out of em' for about 7 months now.

Ugh, I hate Marathons. They are like riding on concrete and give up all of the advantages of riding on wider tires. They do make the bike a lot heavier for no good reason.
Try 35mm Panaracer Paselas. Don't get the kevlar (aka TG) belt. They are around $35/pair (not per tire) through Nashbar, maybe less with a coupon.
Run them around 50-60psi and they'll be worlds faster and more comfortable than Marathons at any pressure and you'll probably go 2+ years without a puncture. They aren't bomb proof like Marathons, but glass cuts usually aren't a problem at lower pressures.
If you get them and don't like them in the first month you can probably find someone else on here who will. If you just want to try them out and see if I'm crazy I could loan you a pair of Pasela 32s for a few weeks. They are almost as good, but you need to run them up around 70-80psi which makes them a little more prone to cut flats.

Road quality determines the flat frequency. For example, travel in the South, on severely degraded roads such as Delridge, parts of Georgetown/Sodo, and areas where the sand from the snow is still in the shoulder is just asking for flats. You can avoid it, but not always.

I might do this. When you say "don't get the kevlar" is that primarily a weight issue?
you can squirt your blue sauce up in my tubes. Sure.

Nope. Kevlar is stiff and the tires don't ride as nicely. Plus you pay an extra $10 per tire for that inconvenience. Since I get less than one flat a year commuting on Paselas without the kevlar belt I can't see why I'd get the kevlar belt.
Note that Kevlar is used in two places in tires. Here I'm talking about kevlar belts, which should be avoided. The other is for the bead of the tire, where kevlar is lighter and more flexible than steel so it allows the tires to be folded. I have no problems with kevlar beaded tires, I just don't like kevlar belted ones. Sadly the Pasela is not available with a kevlar bead unless you also get a kevlar belt, so I only buy them with the steel bead.
