I do not see how you could get less and more sluggish feel with CDV swap if you didn't swap for a even tighter CDV?! Try deleting the CDV all together and see if it improves. Make sure it is well bled, I know it is tight but get it right.
You should feel in more control of the clutch and be able to do faster shifts. The ride can get a bit jerky for a while after the mod as you get used to the new feel and control.
Before I deleted my CDV I had a lot of bad shifts 1-2 and 2-3 as the clutch did not engage right when I released the clutch.
