RodVos; I was able to purchase from my local Parker dealer the 65% module for $10:00. Now I can shoot 65 or 80 percent let off anytime I chose by simple changing the module. I also did not care for the grip that came on my bow it was to much high wrist grip for me . I am a low wrist grip lady. I also did the cutting and drum sanding needed to alter my grip and was able to shape a new custom fit grip that I love.
