but i must say i knew none of this before i did some research...didn't even know anything about spring rates, revalving or anything up until August of last year after a couple months of research, the D2's cost and performance fit my budget, and it also helped that their distribution warehouse is about 10 miles fom me...

OP search H-T for their shock dyno, i think it's still there...there's a lot of info out there and it's best to do a lot of research before making your final decision

I personally like either D2 or PIC suspension products but I enjoy a MUCH firmer (read harsh) ride than most people as well both products allow for custom rates and that for me is perfect.
