So people told you, multiple times,after the first one, try BCY. no dice.
Now after your 5th one, you sign in with this epiphamy of using BCY.

Let's at least get the facts straight. I had at least 3 of those tied on before I thought enough to ask what people thought the problem was.
And you're reinforcing what I've been saying all along. If BCY is the only thing that'll hold.....then it might be a good idea to let dealers know this.
And if your D-loop spinning don't bother you......more power to ya. I shoot my bow a LOT (every day), though....and I can't stand it. I'm also shooting pretty light arrows (327gr). Did this add toMY issue? Don't know.
I can tell you....if it was happening to your new setup.....you'd have been upset.
