Perhaps it is oversimplifying but I believe there are two extremes

1. The leverage swing. The Adam Scott/Tiger type swing. Left hand pushes the club straight back from the ball. Big wide arc, very high hands at the top. Club speed comes from size of the swing arc and club is looped back down to the inside on the DS. More arm speed, less lag on this swing.

2.The rotary swing. Fashionably called the one plane swing. The Vijay/Hogan type swing. Much more around, much more use of the body, more lag

If youre tall and thin youre probably going to hit the ball further with the leverage swing. If youre short and of a bigger build then maybe better looking at the rotary swing. Ive tried both. Im 6'1 and 13 stone and ive found personally the leverage swing is more accurate for me

There is no right way. If we were all built the same we could all swing the same but we aint so we cant!
