I am looking for racquets from the 1980s in a 95"-100" head size that are at least 12 ounces. I have tried the Yamaha Secret racquets, but not really to my liking. I don't know if they are hollow or foam-filled, but when I tap on them, they have a hollow-like feel to them and didn't give me the plow that I was looking for. I currently play with a Dunlop Biomimetic 2.0 Tour, which is very solid, but if was a few mm thicker, it would be perfect. Any suggestions would be appreciated.
