Here are my curved grip rackets. Top to bottom, left to right: NOS Erge Ceramic “Anatomic Plus” NOS Erge metal NOS Biosport Gripper ceramic “Golden Gripper” NOS Biosport Gripper metal 8/10 Sentra Marauder NOS Neoxxline Ergokinetic Does anyone have others? Please post some pictures. I've seen pictures of several Sentra curved grip rackets but I can't find any information to confirm that they were factory made. Mine definitely has a curved grip but it doesn't look as professionally formed as the others. It's also not NOS like the others so some former owner may have messed with it. Anyone got any information about these rackets?
