The Sonic S1's are affordable and perform well (I purchased these based on reviews from others (one local to me) who has had them for a while now. They swear by the Sonics, so I jumped on them as well. We'll see...
what dampening setting do you have the front and rear set to? You said its very stiff, but I'd like to know what settings you have it set to.
