I remember him saying that poly was like cheating but I don't remember him saying that the spin was the main factor. The comparison of the pro players using poly and us amateurs is not very good to me. These guys use a fresh string job every half hour or so.
And I will say that I love fresh poly, it is hard to beat. But even after an hour or so I can tell a difference in the playability, spin and control of poly, let alone a few days. But with the kevlar main and poly cross I am using right now the consistency is way better than a full poly job, no comparison in my opinion.
