I've tried the progressive - 412's,418's,and the 430's - the 430's I found to be the best riding ones of the group - I've also ridden a bike that had the 440's and they were not what I read they would be like - they made me feel like I was riding a rigid framed bike - the 960's were out of my league price wise, but I'm sure they ride real nice - I believe they claim to lower your bike without loosing any travel? Another shock I would consider would be a company called "Works" shocks - I've head a lot of good things about them -
