I've played a couple of times with the DNX 9 and have to say that so far I really like it. I'm pleased that it doesn't feel stiff or harsh, especially after the last batch of 9's (tour 9 & 9ve). The feel of this racquet is something that I'm getting used to, it's totally different than all the other Volkl racquets I've ever played with, not bad mind you, just different. Here's my question: You mentioned that you put a leather grip on and then took it off because it changed the way the racquet played, could you be more specific? It's hard to believe that a leather grip, making the racquet 1 or 2 more points head light, would have a big effect. I have always played with a leather grip and the only thing that's bothering me with the DNX 9 at the moment is the spongy feel of the original grip with a Prince Duratac overwrap. What are you doing to firm up the grip as I know you're used to leather as well? One more question: My DNX 9 came strung with Volkl Power XL / 15L. Is this a decent string or not really? I can't find this string listed anywhere and I really can't judge it because it's all new to me, racquet and string.
