my parker is set at 56 i use muzzy 4 blades when i crank it up to max it gets a little noisey my mathews is at 70 for practicing ill prolly set it at 68 for hunting seems most bows get noisey when you max em out the mathews is quiet i had a friend shoot it so i could listen but 70 is just a hair more than i want to pull on a cold morning after sitting for hours
