Ok i got a few questions for you guys? I currently shoot a Mathews DXT maxed out at 70lbs with a 28in draw. I can shoot pretty good groups all the way out to 50 yards but I'm kinda wanting to decrease the poundage just a bit so I can possible hold the pin just a little bit steadier and tighten my groups even more, do you guys think this would help? And if I lower the weight just a little am I going to be sacrificing alot like penetration, or FPS or would it really matter that much?
