I have a '75 Super Kodiak that I shoot quiet a bit. I have the BH set at 7 7/8", measuring from the string to the deepest part of the grip. Experiment around with it, shooting style, type of string, arrows, etc, all may affect what works best for you. Probably the single thing I did to mine to get great arrow flight was to add an inexpensive Hoyt stick-on elevated rest(@2.50). I know it is not everyones ideal set-up, but its simple, cheap, and made a difference for me. Good luck.
