I played with the Fang Bo B2X again, and I will say that if you can unlock it's true potential, it's seriously deadly. Obviously you can say this for all blades, but out of all that I own, this the one that is very noticeable.
I'm still trying to figure out how to get it to that level, or if it's too stiff for me, in which case, I might buy a b2. But the potential power it has is insane.
My main complaint is that it takes effort to get to the higher level of the B2X. In some ways, I like the viscaria more in this regard. Relatively low effort blade, and you can send the ball quickly.
For anyone who wants to get this blade AND make the most out of it, you have to be active. No lazy footwork with this blade, otherwise you won't be able to get it to it's fullest potential. Along with being active, you need to have proper technique. I think that this blade might suit players who have a more closed angle (not very closed), rather than open.
