Fuji Newest 3.0, chwinn Team in Training, or K2?

If I buy the Team in Training bike, would some of the proceeds go to help fighting leukemia?

I hear the Fuji is stiff, can anyone confirm this?

Also, my local performance had a k2 mod 1.0 or something on sale for $500. Its original msrp was 900, so I don't think it was the mach 1.0. It was white with a thin saddle.

All 3 bikes were on sale, the schwinn and Newest both had msrp at $750 but are on sale for $550. All 3 look like excellent road bikes to get me on the road.

Thanks for any help in advance.
