Update after my first big ride on the Diamond and turning all its knobs:
This thing feels gooooood. Small bump compliance is awesome - cant wait to see what it will do on the brake bumps at the parks this summer. The bike feels very balanced with the CCDBI in the rear (although the CCDBI may need a volume ring - it's a tad soft and not as progressive as the Diamond). Stiffness, tracking and traction over all sorts of terrain was excellent - rocks, roots, sand, hardpack, babyheads, everything seemed easier (this was aided by the LB 38mm rims).
I had 2 nagging issues after my first impression posted above.
1) Stiction at the very top of the travel. I did as recommended here - fork oil on the stanchions, cycle the fork many times, wipe dry. This did not remedy the problem. I may have to talk to DVO on this. Again, it's only at the very top, once it's sagged, it's butter - I don't notice it at all on the trail, so it's not too big a deal.
2) Top out noise. This seems to have been a settings issue. after tweaking with the rebound and OTT, this went away.
The recommended settings in the manual were spot on for air pressure, compression, and rebound, but I currently have the OTT set to like 1 turn from max, which is like 3-4 full turns from the recommended value. I cranked it up to break the stiction but that was unsuccessful, and I didnt see any negative effects (reduced travel, etc), so i just left it there because it still felt good.
