Absolutely great frame. Heavy of course, so quite demanding, but really comfortable and tons of power if you swing hard and hit cleanly. Super stable--does not get pushed around. Serving--unbelievably great, groundstrokes--great, volleys--really good, though this is where it feels the least maneuverable to me. Just note that it's not easy to swing and it takes a while to get used to the weight if you're not already playing with frames this heavy. So worth a demo, and I'd probably expect an adjustment period.
Great all around performing frame. Like most Yonex frames, spin is super easy to produce. I found that it has just enough mass to be super stable, yet headlight enough to be quick at the net. I also like the large sweetspot, especially on returns. Definitely worth a demo.
