If you have too much energy go with a heavier broad head.
I've been shooting 60# 29DL 543gn arrows, with a 200gn Muzzy Phantoms FOC 17% and over 80 KE.... it's slow but I also blow through deer. I hit a buck a little high at 45 yards, knocked him off his feet broke the arrow on the pass through when it hit a tree at an angle. My Trad bows are even more radical, I don't care about speed, I care about KE.
