Here's a short review from someone who never hit with the original 6.0 85. I'll
I'm a 4.0 who just ordered 2 of these matched I've hit with a ton of frames but mainly LM Prestige Mids, Youtek Mids, Dunlop 100s and 300s. The frame I'm currently using is a modded AD 4D 300.
I love the Wilson shaped grip and the feel of the matte paint job when holding the throat of the racquet while hitting. Everything else was lost on me. This is a frame I want to like more than anything. I respect the history and the tradition of it, but this frame suits a very particular niche.
Ground strokes: Forehands were enjoyable, as I usually find them to be with smaller head sized frames. I found this 6.0 to be less whippy and maneuverable than I expected when considering the balance point. My reference frame is 347 grams and 6 points headlight, so I don't think I'm out of line here. Backhands--when coming over the ball, one-handers were more fun than 2 handers. Slice backhands were biting with good penetration when hit perfectly.
Serves: I expected a bit more pop because of the string pattern, 1.20 mm thin powerful poly string I had, and the stiffness rating. Spin was OK on the 2nd serve, control was unbelievable especially on my slice serve which I have issues controlling.
Volleys: Like I said, less maneuverability than expected at the net. Volleys feel great when "stuck" perfectly. That being said, I found this frame to be less stable at 9 and 3 o'clock on volleys than my reference stick (which has lead), and Prestige Mids in stock form.
In short, this is a very unforgiving frame as I'm sure you all know. However, it's also an extremely responsive frame. The feedback from the racquet to the player was simply amazing, even with poly string and a dampener. If your ball is not struck 100% "clean", you'll know it, and have some idea of how and why. Anyone hitting with this frame should walk into the experience knowing they won't get away with anything--lazy footwork, minor breakdowns in form when tired, anything that compromises your ability to strike the ball cleanly will be exposed. This is the particular niche this racquet fills for the modern player. Step on the court for a focused, dialed-in hitting session with this frame and you'll learn a lot about your strokes and mechanics. The frame could be looked at as a tool in this regard. Also, anyone interested in the frame for nostalgic purposes as well should take it for a hit. If you're trying to hit the court for 2 hours and simply produce the best tennis you're capable of, don't bother with the Pro Staff 6.0 85. I don't think this statement only applies to upper end players as I would think even the most consistent ball strikers should expect more out of a racquet than to simply not get in the way of their game.
