Man I love them.
It wasn't love at first sight, but when I managed to get used to them, I realized they fit perfectly my game style.
They are very solid and stable, and perform just like heavier racquets without being heavy. It offers great control, but they are not easy racquets. You have to pu a considerable amount of effort when swinging them, but you're definitely rewarded for that.
I haven't had many problems with spin access, despite it's a 18x20 racquet.
I added 4g to the handle to make it a bit more maneuverable, and it worked pretty well for me.
Serving and groundstrokes with this racquet is great. As I said before, it performs as a heavier racquet without being heavier, so if you have problems playing with 320g+ racquets, then it's definetly for you.
Try both, I bet you won't regret playing with them two.
