RE: the block or black hole?
Bayfire I have the Black hole and it didn't last very long after shooting broadheads into it ,but a friend has the Cube and has been shooting into it with broadheads all season long and it's definetly lasted much longer than my hole .The hole is fine as long as it's field point's your shooting into it .I know target's can't be expected to last very long after shooting broadheads but the Cube seem's to be lasting much longer than the hole. I guess your looking for a target for your new MM so if I were you I'd go with the Cube.
