I recently had this conversation with JB a little while ago in a different thread. But here is my answer. My swing is different for my driver and my irons. From the take away to the finish position, they are mechanically speaking the same. However, my setup is different for each club. I consider the moment I address the ball, to be a part of the swing. Because my address and set up are different for woods and irons, I consider my swings to be different.
