So I've got a bit of a "Rip Van Winkle" perspective on this Blade discussion. I first got on the Blade train with the nBlade MP in 2007 at the tail-end of my DIII career. This was a switch from Wilson Hyper Prostaff 6.1 and the nCode nSix-One 95. Compared to those, the nBlade provided me with way more comfort, consistency, control, maneuverability, and without loss of pace or spin...the usual reasons people switch to a Blade.
The last 13 years I was playing fairly sporadically, so have not really made upgrading top priority and have not tried any Blades in intervening years.. I'm now living in a major tennis state with great weather, playing a ton and competing again. Time for a new racquet! I was excited to try the v7 18 x 20 but was not blown away. Some of the nBlade comfort was still there and my opponents told me I had really great pace, but overall I found it too stiff, too powerful, and too head-heavy. I had to make adjustments to my swing to not spray the ball and, as a bonus, I developed wrist-pain. Admittedly, some of this may have been due to the lower string tension on the demo, but I could not justify the investment in the latest Blade version.
I subsequently demo'd the following: Head Graphene 360+ Speed Pro, Yonex EZONE 98, Babolat Pure Strike 3rd Gen 18 x 20, and Yonex VCP97 HD (not tested: latest version of Prestige MP and the Technifibre TF40 305). I honestly felt that the Babolat was closer to the spirit of the nBlade than the Blade v7, but overall the Yonex VCP97 HD was what I went with for my upgrade. That stick felt like an actual improvement on the nBlade. All the good qualities of the nBlade, plus even greater levels of control and maneuverability. They're currently being shipped, so I hope I still feel the same way in a couple weeks.
