What other sport actions closely resembles a full golf swing?

[acegolfer]

I'm a lefty playing right handed.

I'm a good left handed tennis player with a strong one-handed backhand stroke. My right handed golf swing resembles my left handed backhand tennis swing.

1. weight transfer to forward, but head staying back
2. big shoulder turn to generate power (your back points toward target at top of swing unlike forehand stroke)
3. flat left wrist throughout (even after) impact
4. left hand forward of body at impact
5. left knee extension

The only differences that I can think of are

1. not hitting down
2. stance
