I had the same slivering problem with my yellow jacket target that's why I was considering the block. I'll look at the cube. How is it for field points? I have been having issues with my bag targets hanging up when I try to remove arrows. Not everytime but usually 1 or 2 out of a group. Seems to hang up at the back of the field point as it hits the bag itself. Didn't use to have this problem in the past and I haven't changed anything on my arrow field point setup.
