I've been down this road before and it's really depends on how much money you want to spend. The Wilburs are the best if you can swing it. I had to settle for the Progressive 444 on the rear. At first the preload was set to light. Then I set the preload stiffer than what I thought would be good for my riding habits and my body weight. This worked much better. So after playing around with different settings I am really happy with them compared to the stock shocks.
The stock shocks would buck like a bull no matter what setting I had it on. With the 444s all that has went away.
If you purchase these shocks I have found a little trick that helps a lot on the adjustment. At first I was just turning the top portion of the shock to adjust the preload and it was a struggle. I tried putting one hand on the adjustment housing (top portion) and the other hand on the shock spring and turned both. This makes it much easier to adjust while installed on the bike.
