I have an unconventional driver swing and setup. At least, I feel it's unconventional - I've never videotaped it, so I actually can't tell.
When I setup, I play the ball of my big toe. I setup with what feels like a ton of spine tilt away from target. I hover the club at the ball - certainly this puts the hands behind the clubhead at address. I also tee the ball up by barely inserting a 3.25" tee into the grass - so on average I've got around 3/4 of the ball over the top of the grounded driver.
When I swing, I never get all my weight on my left side. And I proceed to smash the hell out of the ball - 1.47 smash factor is my average (verified on my PureLaunch LM).
Chuck Quinton has a 'bomb your driver' series of videos developed. He agrees (as I do) that the driver is a specialty club. It's a "maximum distance" type club - you already carry a fairway finder, and we call it a 5 iron.
Most don't hit driver off the deck, don't use it around the green, so much like a putter, it's a "one use" club. Learn how to swing it to maximize your distance, and only use that swing with your driver. You'll be glad you did.
