I shoot a Mathews Drenalin with a 29" DL, QAD Ultra Rest, Scott Release and GT Velocity XT 400's and a 100grn head, weigh 355grn. 2-1/2" Bi-Delta vanes, 3 degree RH offset in a Bitzenberger fletcher. Bullet holes more times than I can count as long as I keep my head out of my butt for a clean release. I shoot 295fps + or -.
