I don't flat too often and have always had a stash of new tubes around, so when I would, I'd just put a new tube in and carry on, never giving patching a thought. Now that tubes are getting little pricier, I'm wondering if a patched tube will last, because I have several in a pile with a single small hole in each. A new tube is around $10, whereas a patch kit (like Park's) looks like it might cover 2-3 tubes for $10. But do patched tubes really last long? If they do, is there any specific kit you all would suggest for longevity?
