I would not recommend any block-type target with exposed blade broadheads. They always seem to chew it up quickly.

I have a Black hole and must admit that the arrows do bury themselves in quite far into the target though I have never had one bury up to the fletchings even in the shot-up section of the target.

I also had a block-type target...the cube maybe? It was about 3 feet by 3 feet and the arrows were a bear to pull out. You could shoot it on all 6 sides and I probably still would not have shot it out after 3 years. I donated it to the local club for use on their range. Price was around $80 when I bought it.
