I use glueless park tool patches. no problems whatsoever. I keep my tires at 110psi and I pump up every other day. The tube in my rear has 3 patches for over a year -- no trouble. Spending 2 bucks on a patch kit is better than spending 5 bucks per tube.

I carry the glueless kit, levers, stubby 15, and a mini morph on me. In the event of a blow out, I'm back on the road in 5-10 mins.
