I got a Black Hole and it' s held up for me so far...I' ve shot it plenty of times with broadheads and field tips, and I' m shootin fast. I think the only difference is that the Black Hole layers are vertical as opposed to the Block' s horizontal layers...plus it' s cheaper, but it' s also portable and all that. I got the Hole over the Block so I could save some money, so far it' s got the job done.
