Depends on what you want out of 32mm or 34mm stanchions.
32mm are light, but "flexy", especially if you do some decent downhill. I don't feel that much flex, but I only have 100mm travel. With 140mm+ I guess it'd start moving about.
34mm are heavier, and supposedly less flexy.
I'll be running 130mm travel, wide ass bars, and a 50mm stem. I still may not be 'knarly' enough to noticably flex 32mm forks. But I'll take the weight penalty for a little more stiffness I think.
