Hey guys, I've been doing a lot of reading and am leaning towards the Marathon Supremes. Seems about as close as you can get to slicks w/ good durability and w/o sacrificing traction.

Two questions:
1. is there much difference between rigid and folding if you don't care keeping a spare with you?
2. i currently have 700x35. should i stick with that width or go 700x32?
