Here's badminton giant Yonex at its game once again with the Yonex Nanoray 800. It's more head heavy and stiff than the 700 series, according to the matrix chart.
This here's got 2 more technological advances from Yonex.
FX Plus: a hybrid material incorporated into the end of the shaft near the cone for greater flexibility to address the tougher clear shots we all get from head-light rackets. Looks like a dovetail build that allows for greater movement at the base.
Sonic Metal: new material at the top of the frame that increases repulsion and gives a better clear sound. Since I've yet to hear a Voltric 80 giving me the shivers, I'm going to call bluff on this one.
