The point is that you play your normal tennis and the spin is increased without you having to try and produce more spin consciously or by changing your strokes (although yes, it does play on your mind more).
As we mentioned in the review, this is more cohesive to some techniques than others - for example, those that have western or semi western grips. Something to note is that it's not necessarily about the technology - some of us loved the S technology, but didn't enjoy the frame itself so that may have some influence as to why everyone isn't switching to this racquet. I, for one, loved the spin created, but didn't like the Steam itself as much as I like others such as my APD. Food for thought.
