I have hit with each of these racquets, although several months elapsed between the two sessions. The Dunlop M-Fil 200 seemed completely different than the Wilson nSix-One Tour 90. Where I felt I could adjust with the nSix-One Tour, I didn't get that feeling with the M-Fil 200, although to be fair, I strung up the nSix-One Tour, while the M-Fil 200 was strung by somebody else, using unknown string and unknown tension, but on a lockout machine. Also, I already knew that the Dunlop was more flexible (and with a denser string pattern) than the nSix-One Tour 90, so I was looking for it to be a bit less powerful, and when it seemed to have equal or more power, I was disappointed. This probably isn't much help, but what I am trying to say is that to me, these seemed to be different enough racquets that you would want to try each of them before deciding.
