what i see is diversity. there are so many different levels of ability in the ibo you cannot accomodate all shooters. i agree that the pro class should stay with the 50 yard approximate rule. if you desire to be a pro, this class is for you.
there is no PGA SHORT GAME, or 9.5 foot goal height pro basketball for players that are very good, but short, or a 50 yard NFL for short legged pro football players.
adding classes will not fix any problems. i think the ibo does a very good job trying to take care of all shooting classes and shooting ability, but you cannot change a person. what i mean by that is if a shooter has no business in the hc, it is a moral decision by that shooter to decide if that is the class for them.
