I came in contact with this guy who is very knowledgeable on the subject of Wilson pro racquets and here are some of the things he told me:
1. He refers to Tursunov's racquet as K19 and he calls them K19/K22 instead of H19 and H22 as we call them here.
2. He informed me of the existance of P25 - a 100" racqet, flex 65, 23mm, 18x20, painted like a Blade (Florent Serra)
3. He previously owned Del Potro's actual frame - it's Pro Staff 6.1 Classic
4. Also there are some pros with nBlade 98 extended frames
