1) All of them
2) The IFBB judging.
All athletes should do both the PDI and IFBB. BBing is an individual sport, not a team sport. In tennis, golf, and other individual sports, guys can play in any league they want and with anyone they want. Team sports, sure, you don't want your NBA guys getting hurt in Summer League ABL action. But in a freelance individual sport, men should be able to compete in both.
