Seeing the still photo recently of Zverev's broken foam-filled racquet made me wonder, what are the racquets out in the world, old and new, that a foam-filled. New racquets I know Donnay and Angell but besides that, my knowledge is limited. I believe the Prince POG is foam-filled, although not sure what years and models, also I know that some of the six one 95's are but again, not sure what years and models. Anyway, feel free to contribute if you like. I personal am a big fan of foam-filled racquets.
