Would like to see how people think of the Wilson 85s. Jack Kramer prostaff 85, the Prostaff 6.0 85, and the Prostaff 6.6 85. (Is there any other "modern" 85 that I missed?) How do these 3 compare against each other? I have hit with JK 85 and 6.0 85 (China) and I liked the JK 85 a little better. It feels a little stiffer. Edit: There is a Staff 85 which comes before Prostaff. And I actually have hit with it briefly and it felt heavier I just can't generate decent pace with it. It felt very flex.
