They suck...... Each other together. Two 40yd robin hoods using those things and dam near a third one today. I bought a dozen at the sportsman show a couple weeks ago, went shooting three times and now I'm down to 8 arrows. Two robin hoods, one I just hit the back hard enough to split the arrow, and the fourth arrow broke at the front from the outsert twisting sideways from the "just about" Robin Hood. Talk about good KE though, this is the deepest Robin Hood I've shot, even though it was at 40yds and the tips are wider than the shaft diameter.
