PA--stay 'away' from the Black Hole--I broke the strap on mine just about 2 weeks after I got it, but good old duct tape replaced the strap and to me, did a much better job.
The Block is good for field points, will last you a long time-- like someone here said, but broadheads will accelerate its destruction.

A good 'home made' target for broadheads can be made with the 'ends/left over pieces' from patio door screening--find a factory where they build the Patio Screening Doors---that screening stops anything--of course after a while you'll have to restuff or compress the screening a little. I use two burlap bags and stuff them with the screening and it works just fine and doesn't cost 1/4 the price of the block targets.
