i have the same set up as you. quickspins and a muzzy zero effect. did you put the rest on yourself or have a pro shop do it. That was my first mistake. the pro shop put it on wrong because they tightened the bolt to tight so it would not fall fast enough and they did not set it for center shot. i reccomend unscrewing the arm that connects to your cable slide and unloosening the bolt so that you can just nick it with your fingers and it will move freely. then set the arrow rest for center shot. After i did all this i still had contact. then i set my nock point above 3/16 about 4.5/16.
after all of this it finally worked and i had contact free shooting. if you want to fix your curved fletchings just boil some water and dip the fletching and all into the water. it straightens out all of the curves and doesn't effect the fletching at all.
