I'm currently shooting GoldTip Expedition Hunters with the 5575 shaft. Right now I'm looking into buying some new arrows, and I'm not sure what I should do. My draw weight is set at 70 lbs, and I shoot 100 gr. heads. I've got the options of choosing between the 5575 shafts I currently have and the 7595 shafts. I was wondering if any of you guys know which would be better for me. I was also wondering if I would have to change my sights if I switched to the 7595's or if they would remain pretty much the same as far as how they shoot.
