ask yourself why the driver would be swung different than the sw. what is the primary difference bewteen the two clubs? Length and maybe lie angle but since the driver doesn't make contact with the ground, the lie angle is of no consequence. So length is the only factor. The arms and shoulders still move the club from address to the top and back again. THe amount of time is take the driver head to travel is a bit longer but not by anything measurable with the naked eye. Hence you swing each club the same.
Now swing arc with change but arms and shoulders move back the exact same way with the drive, 7 iron or SW.
Here's the one place that I will differ with you: the driver is normally the only club that you will use where the ball will be significantly teed up off the ground. I realize that some people will tee up the ball a fair amount with a fairway wood or hybrid, but for the purposes of this discussion, let's just keep it to the driver. Also, to maximize distance with the driver one needs to hit up on the ball with the driver, whereas you want a descending blow with every other club. While most of the features of your swing with all other clubs should carry over to the driver, the unique situation of having the ball teed up and wanting to hit up on the ball can result in needing to make subtle changes to your driver swing compared to all other clubs.
