I have noted something interesting...
I have a Prince 03 black team...the most powerful racket i have owned personally...In the beginning this racket had terrible feel.
Once my technique adapted to this racket, it is as if the feel improved. I could use less effort with my strokes, looser on the wrist....less shock and so forth...I probably centred more (and added spin more regularly).
Because of the power of the racket, i would muscle the ball less, and it thus became more arm friendly. But that's technique...But i believe that power should be credited and when used correctly, it can result in comfort also...
Racket wise:
It may be worth looking into the Prince series...their grommet systems may provide less crisp feel, but may result in a larger sweetspot generally, and be softer on off center shots especially.
My advice:
the older you are, the lighter and more powerful the racket should be. As well as a larger sweetspot and headsize. If you are younger, and have very good footwork, i suggest smaller frames and something more orientated to the classic way wilson rackets are made. Smaller frames generally have more control due to their lower twistweight. But they are less forgiving on off centre shots due to their smaller sweetspots.
Personally:
Even though I love the 03 Speedport black team on serve especially, i don't think i will be getting the exo black racket due to lack of control on the groundstrokes. I will be sacrificing on the serve to what i believe will be more important to my game and thats control on the groundstrokes. My second serve is a weapon, and i believe the exo tour 100 racket will even enhance this....so technically its only my first serve that will probably need work. The exo tour 100 is the perfect balance for me specs wise...I have played briefly with the 03 tour (older model) and i could definately feel the flex and comfort and control. Did not test it on the serve though.
