Okay guys,
I was out shooting my bow today, I was shooting the arrows my tech guy let me borrow, and, well, lets say I owe him one now

45 yards and I robinhooded.
Anyways, I am not going to ask about which arrows or what to do with my arrows. I have come to the conclusion that I am just going to get identical arrows as the ones he lent me since they are shooting perfectly out of my bow.
I need to know what the toughest and most durable bag target is. I bought my bag target last year at Wal-Mart. I don' t think it is a major brand. It has a deer on one side, and the other side has 5 bullseyes (Probablly 4" Green lines in a octagonal pattern, with black X' s in the center). It held up to my Hoyt great, but, my BowTech has QUICKLY destroyed it. Every bullseye area has become a weak spot, and I can shoot at 45 yards and send arrows right through these areas. Another thing is no matter where I hit, and no matter if my arrows stops in the target or goes through, it always flings a white cotton type material out of the back of the bag.
I am really looking at three targets, the Morrell Outdoor Range Target. It is big, which is a plus. It has 16 different bullseyes, so target wear would be minimal. This target is 32" X32"
I am also looking at the Morrell 50,000 plus target. I really like the idea of its durability, but, I don' t know if I would like the bullseyes on this target. This target is big at 28" X28" and 12" deep.
The last one I am looking at is the Morrell Super Super " S" . This is pretty much exactly what I want in a target. I really like the idea of having bullseyes on one side and a deer on the other side. It is pretty large also at 24" X24" and 12" deep. I am just not sure about durability.
I like the idea of the " Block" but, I have heard that it is a big pain to pull arrows out of it. After owning a McKenzie 3-D target, I really don' t want to shoot a 3-D target with this bow. I can' t imagine trying to pull these arrows out of that thing.
I just want a tough durable bag target, that will be able to consistently stop arrows moving at 300 f.p.s. or faster, since the arrows I am getting are going to be lighter. Any info will be appreciated. Thanks.
