I really can' t understand why IBO won' t leave the rules as is?? What is wrong with someone shooting in the HC if some physical or personal reason makes this person more suited to shoot in this or any other class why not?? If I had to switch to MBO this would require that I get new sights, different arrows, fletch, and then take another hour to complete the range. BOWPRO please don' t forget that you still have shooters out there that enjoy the idea of shooting as practice for bowhunting and using the same setup to do that. If the idea is to have everyone shoot from 60 yards then I don' t want any part of it, don' t take the freedom of choice & fun out of it. You have a great thing working , leave it alone.
