Thanks for all the good ideas. I'll take a few into account, others wont fit or don't need.

Added to above:
-I'll stick with the tube, but only one*, and I may replace it with for one that can roll up smaller.
-I like the sock idea to wrap the tube, or better yet 2 thin ones that I can also wear in a pinch
-OK, OK, 2 cartridges, but the small ones
-Homemade tire boot is a good idea also, that's in.
-I'll also add a couple single bills (liquid vending machines in a pinch)

NO Thanks:
-Don't need levers (at least for now) as the Deda RS Corsa tires are flexy and loose enough.
-*I'm also fine with (and good at) applying the old-school patches/cement. Dont trust glueless yet.
-No Minipumps too, too big, thanks.

Anyone use those "towels" that are vacuum compressed down to a poker chip size? I might grab a couple next time I stop in to Performance? Even if just a gimmick...it's fascinating.
