What kind of GXP BB do you guys run? Put about 1500 miles on the stock GXP BB that came with my S300s and it's started to click when out of the saddle or under heavy load. I've cleaned/re-greased it and made sure everything is tightened down. I know a lot of folks move to square taper cranksets because of similar issues. But for those of you that do run GXP, is it worth upgrading to a nicer Hope/Chris King BB or will I have the same issues based on the GXP design? I'm fine with buying a new cheap BB every 1.5k miles or so, just didn't know if theres a permanent solution other than going with a square taper solution.
