It does everything well for a player's racket, great directional control, good spin, good comfort, a little sluggish maneuverability wise, very precise, good pop for a pure player's frame, extremely high quality paint job, etc. Everything about it just exudes high qualiyt and craftsmanship, though the sweetspot is a bit small. HOWEVER, it's a lot different from the POG and other "pure" player's frame, because although it's moderately stiff, the feel is decidedly muted which can be kind of eerie. If you like the raw, pinging feedback of the POG, you might find the quiet, muted feel of the Super RD Tour 90 unsettling. It's like playing with a built in sound muffling vibration dampener. Also, the other thing is that this racket kind of cuts through the air funny. The POG has kind of a crisp feel through the air that you can feel. With the SRD Tour 90, the aerodyanmics are a bit weird, because of the triangular beam, it cuts through the air, but it's like you don't feel the racket cutting through the air. It's kind of a weird and unsettling feeling, because it doesn't seem to make the traditional swooshing sound through the air, it's just kind of silent. It can really throw you off if you're not used to that sensation. This is the part of the racket, I most could not get used to, but sure I would adapt if I gave the racket more time.
My only two complaints with the racket are the excessively muted feel and lack of "raw" ball feedback, and also it's eerily silent feeling through the air.
Other than that though, on paper, it's as good as any pure player's frame out there in terms of what it can do overall. Incredibly versatile stick. If you like a muted feel, and don't mind a "silent," stealth swing sound, then I would recommend this racket to any advanced player; but it's not for everyone as it is a bit quirky due to its pyramid cross section and triangular beam aerodyamics.
Best way to describe this racket for me is like playing tennis with a muffler, to some good, to others bad; but no one would deny that this is a high quality frame regardless of personal preferences.
Also, another thing to note is that this racket is vacuum pressure molded like the RD Power 7 and 10 were, and also like Fischer rackets are. The vacuum pressure molding definitely makes a difference in the way a racket feels. Vacuum pressure molded frames have a homogenous, solid yet dampened and crisp, thunk feel to them...just a very CLEAN feel. There feel is just very pure, with no artifacts or fillings so to speak. Like comparing digital sound to analog. Personally, the world would be a better place if all rackets were vacuum molded. Peace, love, and happiness brother.
