Tubes
 

Some one at the OKC meeting was talking about new tubes that don't leak like most I have seen, I think it was Walter Simendinger (nice looking 336 by the way), could we get some more info on that, who makes them, where do you get them, how much more do they cost, etc.

Aero Classic "Leakguard" about $30 for 600-6. Desser has them (among others). Michelin also makes one. Typically a little higher priced. They work!
