that's incredible. I bought the 3 blades. I've shot 2 deer w/ them but I'm still not 100% on board w/ these heads. You have to keep a close eye on them. If you bump them on a branch you likely have to putthe blades back in place. I won't be adding a rubber band to them. You're just eating up ke by putting on the band. the whole point of these heads were that you don't loose ke.
