I have owned 2 different bows, both PSE on my firestorm lite I used a cobra fall away rest, On my new X force I am using a trophy taker. My question is on both rests my arrow fletching would hit the rest as it went by, sometimes the arrow flew fine and other times not so much. The fletchings have some marks black marks from hitting the rest, is this common? am I doing something wrong, or do I need to get it set up again?
