Of course, because you still shoot compounds
Actually, no. I don't. Switched to lefty because of my wrecked shoulder (50 years of shooting a bow and has taken it's toll) and I don't have a lefty compound. Don't intend to get one, either. Except for a few rare ocassions, I only used compounds in tournaments anyway and I can't shoot tournaments any more.
Another thing to think about GMPT, is that even though most everyone out there is hunting with a compound, there are still those who go out with recurves, longbows and selfbows. Even though they only make up some 5-7% of the total, depending on which survey you read, they are bowhunting the way it was originally intended and do deserve some consideration.
