with deer sized game, if your arrows are pushing close to 500 gr. your fine man. with your draw your shooting about 51 lbs. figure 3lbs per inch over that your draw the bow to your draw length. as far as choosing arrows n a set up. there is no magical choice. pick a arrow u want to shoot. i say the cheaper the better, plus those CX dont bend like full metal jackets do. pick what you want to shoot, and figure the weight you want to be at arrow wise and play with that arrow till u ge t the set up are looking for. i shoot a widow 51@29 with 630+ arrow is heavy, make my bow super quiet, and fast enough for me.
