I shoot a Hoyt PowerTec at 29in draw and 70#. I shoot Beamon 340 arrows with 100 grain tips - I sit at about 400 grains per arrow. I have a string loop, 2 silencers, and a nock on my string (don't know how much they weigh). I also shoot with a Whisker Bisquit. I just chronographed my bow on Tuesday at 255fps.
