Tony,
Dingua and other say the 440s are the best. You said you have had both the Progressive 412s and the 440s. Are the Progressive 440s that much better than the 412s, to justify twice the price. I have no back problems, and the stock ride is not too bad for me. I ride almost daily, commuting. However, I would mainly like to help the steering in banked turns over bumps.
My wife also rides with me every week, but for short rides. She complains about the kick in the ________going over bumps and railroad tracks.
Would the 440s be much better for this than the 412s or would the 412s be good enough, especially for the steering? Did you notice a big difference between the two? I am wrestling with $200 extra price difference for the 440s. (I already have the Progressive fork springs.)
