I tried patching tubes 3 different times and failed everytime. I spent more on patch kits and time trying to fix a split (90% of flats are from a spit tube) than just replacing it. I feel that my 1600 miles last year and 1100 miles the year before of bike riding can justify the waste of a few tubes. Just saying.
