62@29 and 57@29 640 grain arrows 200 grain Grizzly Kodiak 2 blade. I'm just a believer in using 2 blade single bevel. I killed 3 deer with it last year...pass-throughs and short recoveries on all, even one I made a poor shot on. I do think I am going to switch to a 185 grain grizzly and a 75 grain steel adapter this fall...1/8 inch narrower, but thicker steel and stronger overall. You don't need a cavalry saber on your arrow...most important other than shot placement is leaving an exit wound, and a narrow, tough, single bevel heads give you the best opportunity to make this happen.
