It sounds like you went the wrong direction with the springs. You really should try the Greens front and rear or try Avid Red front White rear. Those Yellow Avid rears are basically equal to the grey AE springs and the only place I've seen those used is on REALLY high traction surfaces, ie sugared tracks.

Back to springs, I see that you guys running AE springs are all talking about using the green springs and see that in a lot of Pro setups. Back in the fall when I got the Avid springs I was hearing yellow front and red rear. In terms of spring rate this is 2.95 in the front and 2.24 in the rear. I switched to yellow in the rear and it seemed to help but again that could have been the track too. The Avid yellow rear is 2.10, AE green are 2.00.
