combined rebound/comp is not as bad as you might think as its only the slow side that it affects. yes its best to have both separate but problem is most folk dont know how to adjust them properly so end up winding the rebound up too high (slow) to compensate what is a compression problem. having both on same valve takes the guesswork out and lets face it if your muscling a bonny up back lanes or twisty roads too quick your asking for trouble.. lol
in case you dont know the 'slow side' is for braking/accelerating/cornering and not pot hole/bump, thats the job of the internal valving.
but you already know all of this so i'll shut up
