Lets see, I have 5 pilots in the wings.
Lets Pilot 1 fly. He is okay but not great.
Lets drop Pilot 1 and try Pilot 2. Pilot 2 totally fails.
Try Pilot 3, he is okay, but not consistent. So drop him.
Pilot 4,5 are even worse. Drop them permanently.
Try Pilot 1. Repeat everyhting....
Point is it does not matter who you like or hate, to get the best Pilot you need the best instructor/coach.
First get the best coaches in place, that should be the starting point. Otherwise it will always be a musical chair game.
Golf is good, no umpire needed!
