I shoot a 2003 magnatec hoyt, all I know is when me and my buddys goto a 3-d shoot it takes two guys to pull my arrows, my hoyt will sink the arrow about 2 inches deeper than anyone elses bow (PSE, MATHEWS, AND PARKER) my buddys all want me to turn down my poundage. I shoot 31.5 draw at 74# carbons 100 grain tips.Its plenty fast enough for me and it hits HARD.
