I just want to comment on the raising the arms part. For a traditional 2 plane swing, raising the arms is an integral part of the swing. I think that most teachers teach this swing, and so will teach raising the arms on the back swing. But if you have a 1 plane swing, this will just get you in trouble and make it very difficult to stay on plane.

As far as hinging the wrists, it can be a good thing for the right swing. In my experience, working on Jim Hardy's one plane swing, part of this involves rolling the forearms on the back swing to allow this wrist hinge. I found this to take away from my consistency, so I removed that from my swing. I had a lesson earlier this week, and my teacher told me my club was in perfect position in my back swing, so apparently I wasn't wrong to take that out of my swing.

From the lesson, I learned that rather than rolling the forearms and hinging on the back swing, rolling the forearms forward on the follow through is important. This helps release the club and make square contact.
