Factoring in warrenty/crash replacement or lack thereof should be part of your decision whether or not you should buy "X" wheelset. I wouldn't think twice about a carbon clincher as I trained on a set last fall and this spring/summer. They held up great. I'm 165. I am a little more conservative with a full carbon tubular for no good reason other than I've crash replaced a couple and even that gets expensive.

Each wheel maker is different though. Ask them for the best answer. Opinions here mean less than zero.
