Other than the draw length range difference what is the performance difference of the cams? If there is a previous discussion on this I have not been able to find it through the search function so I figured I would just ask.

Only reason I ask is because eventually I'll have a Cougar FC with 1.5 cams and was wondering what I could expect to give up with the 1.5s set at the top of the DL vs the 2.0 cams at the bottom of the DL range.
