If you don't mind upping your grain weight, which would probably help your FOC, the Montec g5's have worked well for me, as well as the razorcaps. Both handled bone very well and in the cases where both ribs were shot through on a bull, the broadhead tips were in great shape.

If you are shooting very low poundage, I would look for a 2 bladed design without bleeder blades for the best penetration but then your blood trail may be a little weak due to a one direction wound channel.

Good luck!!
