TPU punctures

[mcteague]

I've had a few punctures with TPU tubes, about the same frequency as butyl, but find them much more difficult to patch. The other day I got a nail in the tire and the tube always seems to have the hole right at the folded edge of the tube and with a ragged hole. I know TPU has little stretch and holds it's shape but, at this point, they seem great except for patching.
