I do not have the chance to try these rackets. In fact, I have only played with very few modern hi-end rackets as I had given up on badminton for quite a while and pick it up again recently. The racket frame and shaft also taper towards the end, speed is decent. It might not match the arc-zs, but should be one of the closest in the market. Notice: I did NOT play with the arc-zs, it's only my guessing.
