[ChangeMySwing]

I don't agree with you on the Mark Evershed topspin (he is not doing anything different than Tomasello during impact)...what you're calling topspin is impact swivel or what Hogan called supination..

By topspin, I mean that the swing feels similar to a tennis stroke, and not that it is faulty in anyway. It just feels different when I change my focus from my forearm to my right hand. I feel more lag pressure focusing on my right hand, but more speed and 'whippyness' when focusing on the right forearm...
