So Yonex has a new innovation out - the DUORA.
As I watched the video, two questions cross my mind.
How do you construct and fuse a frame with two separate materials?
If each side is of a different shape, must I constantly keep tabs on which side I'm using to hit so that I am getting the optimal backhand or forehand stroke?
Well, at least this one sounds more scientific than sonic metal...
Duo face, Radical concept. Worth a wait.
