I recently bought a HD3 with the cane creek DB inline and I have been very impressed with that shock. Very responsive when you need it to be. Did a continuous 800m descent on Saturday and it worked very well. Planning on taking that bike to the Alps in August.
My partner has a Fox Float X on her Pivot Mach 6 and that is a very good real shock too. very sutble but also has the CTD thing which works well.
BTW, great bike too and climbs wells, loves single track and awesome downhills. A friend has recently started riding one and compares to to something between a SC Nomad and Bronson.
