Just bought an 04' Patriot Dually. Maxes out at 74/75 pounds, which is where i will shoot it. I have two dozen Gold Tip XT 5575's. Are these arrows a good match for my new set up? iM STILL DEBATING ON 100GRAIN HEADS OR 125's. Not sure if i want the speed or KE yet, although, really, i have both with either wieght. But will these arrows do the job?
