What do you carry with you?

On patch kits, the vulcanizing glue dries up so fast that once it has been used, you have a whole bunch of patches that can't be used because the tube is all dried up. Unless you buy a whole bunch of new tubes of vulcanizing glue.

I have a garage full of patched tubes but I don't have a lot of confidence taking them out as spares because too often I still hear leaks after patching them up.

So I have a stock of brand new tubes too.
