I'm wrapping this one up I'm going to shoot it for a month or so before final tweaking and putting the finish on and move on full time to the 60" Carbon , Just a couple notes on this bow ,I'm contributing a lot of the performance & getting a lower brace height to the ACS type limbs, if you look at the limb pic a few pics up you can clearly see the concave limbs in conjunction with the carbon got me extra FPS & a lower brace height and more narrow limbs ,but due to the concave limbs it was a real lesson in tillering and getting it to lose weight & didn't help with figuring carbon in the stack but after the 60" is done as a standard bow I will have more stack info !
