Ok guys, I have a 64" double carbon Adcock with micarta riser. I need to know what is the best brace height and nock height? Thanks again guys

I have a 64" and the Master said 6 3/4" to 7 1/4".  This is a take down that likes 7".  My nock is set at 1/2", but all my bows are around there.  My little one pc 62" he has 6 7/8th to 7 1/4".   They are out this world!(Roswell, I think the UFO little people taught him some tricks)

I don't know if you have a OL Adcock or a A&H but they are the same, I have two A&H's long bow and a three piece both 64" #54 I draw 28" they both work best at 7 1/8 brace, 1/2 nock.

I have my brace hight set to 7 1/4".
