I can say that I tried my 82nd at 70 lbs with a .300 spined arrow, and had to trim down the arrow to 28" and back it down to 68 lbs before I got completely satisfactory arrow flight.
Glad you posted,because it was your bow that I ran through AA and it took exactly what AA said for it to be right with broadheads if my memory is correct.
