Hi Ray, tnx for your response!
I have been running lately to up my condition, so I don't think that will help me more. Also, I'm not out of breath during the tennis, I just feel that I handle my racquet too slow, even when I'm focused on early preparation and my footwork.
I have the orginal grip on my racquet, and an overgrip. So I would think that changing that to a lighter replacement grip, would make it head heavier, and therefore slower?
My current setup varies. I have played with a syngut at 25k, after that changed to the same string at 22K. Right now I'm als experimenting with a poly at 16K, but have only played with that for half an hour, so can't really comment on that.
BTW, I'm using the 2011 version (black/red), not the 2012 version (red/white). The "normal" blx Blade was not on my list, it's too close to my current racquet I guessed....
