Golf is my primary hobby and pipe smoking takes a close second and I integrate them as much as possible. Anytime I'm working on my golf game and playing practice rounds I try to smoke a my pipe. It helps me in a few ways, A.) I enjoy the smoking of my pipe while in between shots, or waiting in between holes, and B) clenching a pipe helps me hit better golf shots.
Hitting shots with a pipe in your teeth, helps you relieve tension in your body. One of the number one killers of a golf swing is tension in your swing, and when you're holding tension in your body, you'll notice that it goes up to your jaw. If you can clench a pipe and hit golf shots, and not ruin your stems then you'll find that you're much more relaxed. This in addition to using proper swing mechanics, will probably hit much better shots.
Win/Win in my book.
I'm not saying that clenching a pipe is going to be the key to learning how to swing a club, but it's a tool to help someone that has problems with tension in their swing.
