New to this thread, but interesting info, and a really cool idea. I was curious as to everyone's opinion on broadhead performance, not only in the test kit itself, but in real world hunting experience. Have you noticed shape or overall size (not weight) of the broadhead make differences to you, whether in flight or penetration? For instance, the rounded shape of the Bone vs the harder angles like the "standard" triangle shape? Length differences like the Grizzly vs the Eclipse? Vented vs non vented? I've watched a lot of broadhead tests, but curious as to real-world experiences from everyone. For those that donated broadheads, are you still shooting the same head that you donated, or have you moved to a different one, and why?
