I think my draw length was too short. The shop set me up at 29" but my bow arm was bent too much for my comfort. So tonight I changed it to 30" and it felt so much better. I could hold alot steadier on the target and my arrows seemed faster and flatter. Group size shrunk in half too! Pinwheel has my setup now at 275 fps, 532 grain total weight for 89 ft-lbs KE.Man I love tinkering in the off season....
