I have a couple of Aerogel 300 frames that I cracked (my grip was too slippery and the racquet slipped out of my hand when I served). I threw these into a closet and bought some replacement frames. however, I mentioned my story to a friend, and he said he thought Dunlop would replace them. I'm pretty skeptical, but was just wondering if anyone has been able to do this and who did you contact at Dunlop? I bought these privately, so I wouldn't be able to go to a store. Thanks!
