To respond to all who answered (and thank you)...
For those of you who said it wasn't worth the time and effort, I didn't have much else better to do.
For those of you who said a new tube is cheap, you don't know my financial circumstances. You also don't know that I'm not part of this throw-away society.
To Bill/RC - Thanks for telling me about REMAs. Those are the ones I use and prefer and didn't know they're meant to overlap. THanks for the pic.
For those of you who think I don't know when a hole isn't "already there", I do know a thing or two about bikes.
To Choddo/Trakhak - thank you for recycling as you do. Some of us appreciate it. As for the tubeless thing, I just looked into that on-line and it seems you need rims to go with tubeless. Which isn't going to happen anytime soon.
To PRJ - Most of us DID NOT pay such a ridiculous sum for their bike! Stop trying to demean people with ******** statements. Even if you're the owner of this site, you have no idea what people spend on anything.
To John - that's exactly what I do too.
