The one part of the equation I am surprised no one has addressed so far is his arrows. What grain weight is he shooting through this bow? Is he some speed freak under the compound bow delusion of chasing the 300 fps magical barrier? If so, he might be trying to throw underweight arrows to gain perceived advantages. Frankly, I think I would be likely to start with 550 grains of the combined shaft, fletch, and point weight simply because this bow is performing respectably well above the "100 + draw weight = respectable fps" formula.
This bow is clearly storing and returning a decent amount of energy and if there is not enough mass in the arrow to absorb that energy then it has to go somewhere.
Or maybe I am wrong. I dunno. I happen to love the look of this bow and am feeling covetous emotions in regards to said bow.
