RE: Light Arrows
May I suggest a CX 3D Select 200 for your set up. You'd get the most consistent and precise hunting/3D shaft that I've ever found and a light weight. I shoot mine with a bit more poundage than you are (63 to 65#) but depending on fletch/wrap/b-head combo I choose, I generally end up with a finished arrow weight in the 330 to 345 grain range. I'm betting it would make you a perfect hunting/3D arrow. Good luck and good shootin'
