Just an observation rather than a cry for help really & interested to know what others find.
I have a Turner DW 5 spot and tend to setup my travel as per instructions – 17mm of sag on the rear shock (Dave Turner's instructions and most seem to do the same) and about 41-42mm of sag on my 150mm Revelations – that's somewhere between the traditional 25% sag for XC riding and 33% sag for more "all mountain" riding, which is about how/what I ride. I have noticed however that I always seem to come back after a ride around my local loop with the O rings at the bottom or off the piston on the rear but only 2/3rds to 3/4 of the way up the stanchions on the forks.
I know DW suspension does seem to eat up the middle proportion of its stroke travel quite easily due to the nature of the design which might account for the difference a bit but I suspect I probably ride too far off the back of the bike on the tricky stuff and am unweighting the front wheel too much which might explain why I don't have much confidence with the front wheel washing out (which means I naturally ride even further back away from the oncoming accident – viscous circle).
