Well, I now have a 64", 52#@28" ACS CX. I traded the 66", 45# limbs for the set of 64", 52# limbs. The 7# difference does not change the smoothness, the quietness nor the deadness in the hand of the bow. However, it does redefine fast for me. I'm shooting 30.5" Easton Axis 400s with 125 gr points and 29" Beman MFX 500s with 125 gr points. The 8.4 gr/pdf Axis 400s groups with the 8.1 gr/pdf MFX 500s. The bow shoots flat to 20 yards and then I have to aim higher just a hair at 25 yards. It shot a 2013 which weighs the same as the MFX 500s through the chrony at 195 fps Saturday. That is with a string set up for hunting.
This bow is a phenomenal shooting bows. I've made similar remarks about quite a few bows. I would have to rank the bows I've owned in the following order:
1. ACS CX
2. Crow Creek Black Feather LB
3. Dale Stahl T/D Recurve & Hybrid LB
4. Border Black Douglas T/D Recurve
5. Robertson Vision Falcon T/D Recurve
They're all great shooting bows. The only two that are presently in my stable of bows are the ACS CX and Crow Creek Black Feather LBs. There are some other great bows I've owned, but these rank as my top 5, IMHO.
Below is a pic that is similar to my ACS CX. It came from the A&H site. The Cocobolo on my ACS CX is a good bit darker and the riser was made by OL and the limbs by A&H.
