If you are a right-hander, and play golf with a traditional left-hand set-up (a la Mickelson), I think it would be back-hand with the right arm, the left hand being just there for the ride.

I agree with those that suggest that the left side should be the more dominant (in golf) for a traditional right-hand set-up, where the movement would be like a left-handed back-hand. This does nothing to help the right-handers like me that play what is regarded as right-handed, unless they can persuade their left sides to be more dominant............... too late for me to change to the 'other side', which is why the left-hand back-hand topspin swing thought helps me

Another few instances where right-handers are coached in left-side useage, are
'left arm straight'
'left shoulder behind the ball at the top of the swing'
'left knee towards the ball on backswing'
'left wrist flat'
'left hip starts the downswing'
'left hip turns through' etc, etc.

Sorry, starting to ramble now but I do feel it makes sense to have the more dominant side as the leading side of the golfers set-up.
