i just put on a trophy ridge drop zone rest on me pse beast shooting a 70#s with 30 inch easton 2216's i am getting a left paper tear that the guy told me was becouse my spine is to weak when i bought the arrows from the archery shop they said they were fine with my set up. so my question is could the left tear be becouse the guy that put on my rest was shooting it and not me and is paper tuning really that important they group fine at 40 yards and that is the farthest i will shoot at any game animal?
