Rebound adjustment on 04 & 05 MC and EC

[FFRDave]

I have an 04 MC 250 and an 05 EC 250 (recently 300).

I noticed that my MC is actualy easier to ride than the EC. That MC just flys around corners, but on bigger hits the rear shock rebounds too quickly, smacking me in the butt.
I know that the knob/wheel under the shock controls rebound, but the book only tells me to turn it clockwise for an adjustment. If your perspective is above, then clockwise is one direction, but if your under the bike, then clockwise is the opposite direction.

If I knelt on the therottle side facing the bike, which direction (forward turning or reverse turning) would slow down the rebound. In this scenario, forward is moving the knob from left to right (or Counter clockwise as veiwed from above). Thus, reverse turning would, be from right to left (or clockwise as veiwed from above).

MY EC should gain manuverability if I set up the suspension just like the MC (except the MC has 50mm shocks and the EC only has 45mm shocks).

MY EC has about an eighth of an inch of shock extending above the top tripple clamp. I have about 4" of sag at the rear end (I know thats way too much). I think If I run the forks level in the top of my triple clamp, I can reduce the rear sag. Then, If I copy all of the compression and rebound settings as found on the MC (minus some rebound speed as noted above), I should be pretty close.
I may want to compensate for the smaller fork tubes by adding a couple clicks of stifness to the front shocks.

I have the EC set up mainly for long (like 20 or 30 miles long) sandy whoop trails and some sand dune jumping. I have owned the MC for two weeks, and just love the way it handles in regular soil. My sand dune area has been closed due to disputes with farmers, so I have no clue how the MC will run in deep sandy whoops with ist current set up.
