I know that some of you have played with the Ti-7 and like it, but we haven't had many comments about the new Iso 750. On paper (computer screen) these two racquets seem to be quite similar, both stiff, head-heavy Muscle Power Ti-mesh racquets designed for an offensive, smash-oriented game. The prices are even about the same. Has anyone tried both racquets? What is the difference? Which did you prefer and why? If you have played with both, how does the Iso 750 compare to its predecessor, the Iso 800? To the Iso 600? If anyone has played with the 750, but can't compare it to any of the above racquets, how do you like it? Is there any other racquet of this type (head heavy and for offensive games) that you liked more than any of the above racquets Thanks
