I have an 08" Slayer X with 13" Super Magnum limbs and the M-Pro cam set up. I have a feeling that sometime in the near future I'm going to want more speed, so I'll be considering selling the bow for something faster or keeping it and changing the cam to a dual cam set most likely.

If I were to change out the M-Pro cam, what are my best options for speed without giving away too much in the way of smoothness of draw cycle. I would still want a 75%-80% let-off.
