I can get my 5575 to tune very well at 70 lbs 29.5" draw out of my solo Pat with 75 grn and 100 grn heads. At 125 and 70lbs 7585' s may work better for you.

I also shoot 7595 out of the same setup (little rest adjustment) just as well with 100 grn tips.

Watch what that bare shaft is doing and adjust accordingly and you should get close
