First, a little background. I'm a 54 yr old 4.0/4.5 player. Coming back from a shoulder injury that kept me out for almost 15 years. Have tried many sticks since my return and have settled on the Babolat Anniverysary Pure Drive as the weapon of choice. Now to the Slaz... First, their appearance is simple and clean. Nice lines and balance. Slightly heavier than the PD, but fairly easy to adjust to. A little more headlight than I expected or prefer, but that can be fixed with a little lead tape (not installed for this review). My sticks came unstrung, (my choice). At first I put in Obdura Co-Poly at the lower tension range. Went to hit with a friend I usually hit with. He knows my game and can judge on what this racquet gives me. Let me say that the stiffness of the racquet and the stiffness of the string were Too Much for my joints. After a short hitting session I knew this wasn't the right setup. Dissapointed, I put the Slaz in the bag and went back to the PD for the remaining session. When I got home, I cut out the co-poly and installed Babolat Addiction at 54lbs. Went to play again this morning for a doubles match with a couple of my buds. BINGO! Light Switch on! Night and Day performance!!Soft feel with Crisp Serve and Volly. Now This is what I was hoping for!! Played 4 sets (rotating partners after each set).....Never Lost a set or service game. Great response at the net with accuracy to rival any stick I've played. Not quite as much pop on the serves as I usually have, but enough to keep opponents on their toes. Placement of the serve was even par as my usual. Groundstrokes take a little more focus than normal, but the pace and depth were very acceptable when using proper technique. (not for a lazy swinger IMO). Spin seemed a little less, but controlable. Overall, If you have a solid game these sticks perform well. But if you become a little lack-a-daz-icle and don't focus, these will let you know in short order. For the $$$, these are a very capable racquet for a good player. (plus their appearance is kinda cool!. Had a couple players from the adjoining court make comments on how sharp they look) Find the right set up and I'm sure you'll be happy!!
