This will be my first year bowhunting. I recently purchased a Pearson Quad 440. So far I' m quite happy with it. I had it paper tuned at the shop I bought it from and I can shoot fieldpoints in a 3" group at 30 yards. I decided that I wanted to use G5 Montecs to hunt. I bought the preseason broadheads (and hunting broadheads)so I could practice. I eagerly screwed them into my arrows and started shooting. I knew that broadheads would fly differently than my field points but I was disappointed to find that at 20 yards they hit 9" low and 9" left of my aim point. Before I started moving my nocking point and rest, I decided to ask the pro where I bought the bow. He didn' t seem at all suprised. He checked my broadhead/arrow alignment. It was good. He then suggested mechanical broadheads. I told him that I had already purchased these broadheads and would like to tune the bow to use them. He did everything in his power to convince me not to tune the bow! This seems to go against everything I read on the net. He said that sometimes you just can' t get certain broadheads to fly right. He went on to say that if I try to make my field points and broadheads strike the same place that " it' s a compromise" and that I will be giving up accuracy. He pointed out that if I tune the bow to the broadheads without also tuning it to field points that I cannot shoot field points anymore (with the season so close, I could just use my expensive practice broadheads). While extolling the virtues of mechanicals, he spent more time telling me about their short comings than convincing me why I should use them. My question is, is this guy an idiot? What did people do before mechanicals? I have also read that some people just move their sights to compensate. If I do this, the arrow will strike my aimpoint but will it effect penetration due to poor flight?
