alright so i get the idea that the front has to be heaveir, but how do you figuire this out. inst the feild tip of BH heaveir then the fletching. Will my local pro shop now how to figuire this out. I'm interested in finding out everything that i can, obviously i wanna make it the best shooter that it can be. that way i can only blame myself, lol . anyways right now i am shooting a Bowtech Patriot set at 70 pounds with probably a 30 inch draw which is a tad to long. I'm shooting a fall away rest with a release. I have a dozen Carbon express Terminator hunter arrows "6075" that are 30.25 inches from tip of feild tip to the end of nock. They have 125 grain heads. I also am shooting aluminum Eastons XX75 Gamgetter 2 2117 that are 31.25 end to end. The carbons came with the bow and the aluminums are from a previous bow. Neither fly perfect with the rear going in a round motion. My be just my shooting skill or lack there of. I had the bow paper tuned this fall. i think that neither of these arrows are prolly correct. I can hold alot better group with the aluminums but the tend to drop faster then the carbons. I would like to get some new arrows that are dialed in for my bow. I cant decide if i like aluminum better or carbon, from what i have heard it is just a personal preference. What would be some arrows in carbon and aluminum that you would suggest as there is somemany out there. I am thinking about getting some that are set up as a lite setup and some medium to heavy to see what i like better. Thanks for all the info and help guys!
