As a bigger racer (I am 5'10" and 150 lbs), I race on clinchers and do NOT have an issue with the wheel weight. And FWIW, I race road races and crits on these wheels (they are carbon Zipps, however). As others have said, for the PITA work with a tubular - stretching, gluing, etc., I wouldn't worry about it.

I have a teammate who is significantly smaller than I (108 lbs, and probably about 5'3") who I just talked out of tubulars for the same reason. The weight difference wasn't going to make that much of a difference to her, even at an elite level of racing.

If you are primarily doing tris, I would look at a clincher before a tubular.
