From watching the video's and using the blade itself it can be used in all types of grip's.
I am a shakehand player so for me the ball to the front feels best.
I am still getting a feel for what it can do but notice because their is no handle this paddle can definately bring a new experience to the game.
I have seen them for sale on e bay or amazon for over 200.00 and all sold out.
because i look for and design unusual blades it was easyier to just make one.
