I found a Glen Del Full Rut target 3 years ago for $80 that had both antlers the same side. No big deal I bought it and have shot countless arrows into it. It has the 4 sided insert that you can switch around but I have only shot one side the last 3 years. I am very happy with it, especially the price I paid for it. Now,mybow is not a "speed bow". The only time I ever chronoed it it shot low 260 range with my hunting setup. But I've never had a pass through and I never shoot broadheads into it. I leave it set up on my archery range with another 3d target, a bag and a broadhead target but I do try to cover it so its not in the weather so much. I think they would last longer that way.

I have neverowned a block 4X4, I assume its designed similar. I dunno, but I really like mine.
