I used the V7 Blade Pro which, aside from paintjob, is exactly the same. I used it stock except a leather grip.
It was pretty powerful due to the higher swingweight, higher launch angle, solid and stable. Good spin, I wanted more control.
Didn't work for my flatter mechanics.
Compared to the Pro Staff V14 (my main racquet) it has a higher launch angle, more spin, more power, and less control.
Equally stable but the Pro Staff swings faster due to its balance and lower SW.
I loved the feel of the BP. So plush and so pure. It has a more direct (less dampened) feel than the Pro Staff but they both give good feedback just different how it feels.
The normal Blades are totally different racquets and much easier to use. The BP is a classic, box-beam racquet.
I used Black Code and Big Banger Original at 50lbs and still felt like the BP needed more control. I was very surprised by that.
