Not sure why it's called a right sided swing.I think it's just a marketing coin.
It looks to be a bit like S&T where the weight is kept left at the top of the backswing.On the downswing,it is basically an arm swing.In Edwin's own words,"the arms and club should move faster than the pivot."
This pattern can work for some people as all patterns could but I don't see many hall of fame ballstrikers doing it.
My opinion is that it can work but it's not a high end pattern.
