I think it makes sense to move almost every line of racquet towards demands of modern game. Heck, even Federer is struggling against Djokovic and Murray.
I admit having my own intrest here because as I really like my bio 200, I wish it would be a tad stiffer and some wider ss. Especially when the match moves towards baseline bashing with extreme topspin.
