Costly. Now, in all my years of shooting in organized archery (57 now) I have ONE. B/4 5 spot targets we shot 1 bull. Now, I owned 2 shops/lanes for nearly 20 years. I have no idea how many indoor/outdoor shoots + indoor/outdoor leagues I have attended. I have posted indoor 300s, outdoor field 560s & animal outdoor 560s. Those are all perfect scores. I have destroyed nearly a Dz. arrows in an indoor tournament-blowing the ends off my shafts but not a Robin Hood. I think it was mostly the way aluminum shafts were made back in the day & no, I don't feel cheated. I have seen archers (back then) stack 5 arrows in the spot & a quarter would almost cover them but NO Robin Hoods. Lot's of busted nocks & blown ends of shafts. Sorry to ramble.
Enjoy your excellent shooting & be glad we now have the 5 spot targets.
