I just received my contract through Wilson as I am a teaching pro and I chose 2 of the 99S racquets. I will be getting these soon and I will try and add to what I wrote back in October.
I also ordered a reel of Pro's Pro Concept (co-poly) 1.38mm string in hopes to gain a little bit of duribilty in my poly string and not break the bank. The reel was $47! Even if I break it within 3-4 hours I can just pop in a new set no problem.
Follow up to come.
