OK, after taking my first flat on glass with my new bike - I'm interested in the thorn proof tubes - what's the name? (any name?) --- and how bout the slime tubes --- harder to replace than a regular tube?

I'm changing out the tires (or getting another wheelset) for a better mtb tire as that's what I originally got the bike for and then the commuter was stolen) - and could always put on an armadillo but I have in mind a different tire (werewolf)
