I have a new Bowtech VFT Sampson, and I have never shot a faster bow. I have the draw weight set at 85 (90 pound limbs), 30 inch draw. With a 3-71 ACC, 125 point, 4" feathers, 29-1/2 inch shaft totalling 454 grains I am getting 316 FPS. And the holes are absolutely perfect. With Gold tip 7595 XT' s, 125 point, 4 inch vanes, 29-1/2 inch shaft totalling 442 grains I am clocking a scary 332 FPS. Holes are not perfect but not too bad for a lightning strike. The Goldtips are under spined for this bow at this draw weight. I do alot of speed, spine, weight arrow study. I have scale, paper, chronometer, etc. so if there is a combination that you want some information on I would be happy to shoot a few and let you know what happens.
