Mainehunt,

I'm shooting virtually the same set up as you. 74lbs 30" draw 29.75" 7595 shafts and I am shooting a 125g head. I think if you tune the bow to a 125g head you should see little diffrence in arrow flight. You'll loose a bit of speed and your tradjectory won't be quite as flat but I'm cartain the 125 g head will be the best fit for your set up. There's only one way to be certain though. Buy some 125g field points and give then a try. I think you're likely to find that a 125g head will fit your set up just as you'd want them to.
