My friend is a Yonex rep... I just asked him to get a Ezone DR 98 demo for me. He wants me to try the VCore Dual G 100, thinking it might be a better fit for me. I find that the Vcore specs are very similar to my present racquet, Prince Textreme Warrior 100, so I'm not interested . I want to try a racquet with a little more weight , etc. I find the DR to be very intriguing , based on all of the rave reviews.
