been using the lunar lites too. half the weight and TWICE the price i might add. no problems...

BUT, they are thin and a bumbling job of installation can puncture them easily.

i have no reason to believe that flats should be a problem. after all anything that can get through a hard (compared to a tube) tire tread and casing should have little trouble getting through a tube. right?

BTW, i run tuffy lite tire liners too. still haven't punctured..
