What can I say, I shot dozens of bows last March at the W.V. trad/primitive expo. This one felt like something else to me. Incredibly smooth and wonderful shot experience... it was begging for me. Also, nothing comes close to a beavertail grip. I got a 66" 43# that I draw to more like 45#.
I believe Abe told me 6 7/8 up to 7" brace height (I'm sure of the upper, but not sure about the lower). I can try to dig up the e-mail he gave me with all the recommendations for his bows. I'm sure he would e-mail you the same if you ask.
I've found that mine is most quiet closer to 7" or just a gnat hair over 7. Then I have silent darts.
