I am black bear hunting in Ontario this fall and am wondering about broadhead selection. I am looking at the Rocket Aerohead ultimate steel, the thunderhead and the Montec G5 all in 100 grains. I have used the thunderhead in the past but have heard great things about the Montec and the Rocket broadheads. I am just not sure about the rocket because the cutting diameter is only 7/8". What are your thoughts? Thanks.
