I think the title of the thread is "what sport actions closely resemble a full golf swing." Therefore object used in the swing and placement of hands don't really matter. The precision needed is very similar. In hockey, it can be necessary to shoot from approx. 64 feet, and hit a target, yes hit not land on, that is maybe 5 in. in diameter. It takes as much touch on a shot like this as a 55 yd wedge, provided you don't hit some wedge full at that distance. You can sweep the puck, just like you can with a driver. If you bottom your swing out at the ball while using your driver, then you are swinging wrong. With both swings, you are supposed to hit up on the object. This means both swings bottom out before the ball/puck. If you bottom out too soon with either you will top them, too late you will push them.
I play hockey and golf left handed. I was an allconference hockey player in high school and am a 9 handy in golf. I can shoot around 110 golfing right handed, but a 10 year old kid could out shoot me in hockey if I tried right handed. Bet ya a random guy off the street couldn't get the puck in the air but could hit a 150yd drive. Should probably be pretty good at both before you say which one takes more precision. Somebody who is athletic can be a 15 handicap in 2 years with a little work. I played hockey with people for 8 years who had a worse slapshot than my sister.
