ej,
So you are saying that it's up to US to police this ruling? SomethingOFFICIAL needs to be posted at registration about this particular piece of equipment as it has become quite popular and is unknowingly being used at IBO sanctioned events ....due in part to the earlier announcement that it WAS legal.

So WE have to be the "Bad guys" and protest a fellow competitor who is unkowingly shooting illegal equipment? Don't put that on us........I had to remove mine as per the rules because I was made aware of it , but I'm not about to ruin a fellow shooter's weekend who is "cheating" by definition because he doesn't have a clue.
I would rather lose to someone who shot it and did not know it was illegal, than protest it's use.
Didit bother me that after all this I shot with a guy in my group on Saturday who had one on his bow? Sure did........was I going to report it? Absolutely not because it's not his fault.
