So this is more of an "I want to see it" than an "it's been done and here are the results", but I would so like to see the following shocks being put to the test for everything from weight to plushness, to adjustability..

Fox DHX Air with Kashima (Possibly the new RP23 with Adaptive Logic?)
Cane Creek Double Barrel Air
XFusion Vector Air HLR
Rock Shox Vivid Air R2C

Granted alot has to be said for what bikes they are on and what shock would better suit that bike as well as... **** nevermind there are too many variables..
