RE: H.C Rules Question?
I copied this from the rules section:
"If an archer wins more than once in HC at a qualifying event for shooter of the year, or wins either the National Championship or World Championship during any one IBO shooting year, that archer must advance to another class for the entire duration of the following IBO shooting year."
Since it doesn't say Indoor World Championship, the answer would be you can shoot HC. If you win Indoor World and one of the Southern Triple Crown shoots - you would have to advance the following year. Hope this helps.
