This racquet has tons of spin but does take a few minutes to get the launch angle right. Once you do the ball lands deeps and heavy at the back of the court. I would strongly encourage anyone interested in the 99s to try the Steam 99 LS as I was amazed how stable and maneuverable the 99 LS performed. In fact, the 99 LS may be my next racquest (currently using a BLX Pro Tour and Pro Staff 6.1si before that).
I am getting back into tennis after an extended break and it's time to upgrade my weaponry from my Hyper Hammer 2.0 (that dates me a little) to something a little more modern. I will eventually work my way back to somewhere between a 4.0 and 4.5 and I as I've grown older I am much more of a baseline player than a charge-and-volley type of player. I demoed the Wilson Steam 99 along with a comparable Vokyl and Head. Here's what I liked about the Steam: looked good... felt light in my hand... seemed to give me good spin (especially on slices) and good snap on my serve. There are some dislikes as well. Control wasn't as pinpoint as I would have hoped and off-center hits carry a heavy penalty. I may demo a few more... maybe not. If I were to buy a new racquet tomorrow, it would probably be this one.
A great playing racket. Caught me completely off guard. Yes, the spin I believe is more than more conventional rackets but not a huge difference for me compared to my Babolat Aero Pro Drive. The big reason why I bought this racket was that it played so comfortable in comparison to the APD while still offering all the control and maneuverability. Very solid choice for people who play with control and power and want some more pop on their shots.
