This loop is about as good as we get around here, but it's not even "brand new asphalt" smooth, so I bet a lil lower pressure might help, I'll try it and see how it goes.

From what I've read, the light butyl tubes still don't have the suppleness of latex. I tried Conti Race Light tubes and didn't notice any difference over their regular Race tubes (both in GP4Ks). Haven't tried Supersonics tho, if I have issues with the Michelins, maybe I'll give those a try and see how they feel.

I read somewhere that Continental doesn't recommend latex tubes for use with their tires, I'm sure it has nothing to do with the fact that they don't make latex tubes. lol
