Thanks for sharing your pics, joe. Nice examples.
I started with the Taiwanese Pro Staff Mids. In the mid to late 80s I used Prince frames. I got into the Pro Staff after the SV factory closed and didn't know to (nor could easily I given my location) tap into the used market for SVs and Chicagos.
I consider them "harsher" than the SV. According to the recent
Wall Street Journal article Courier and Sampras "hated it and thought the old frames were better. Courier suspected the St. Vincent rackets were superior because of the volcanic island's humidity. Sampras thought the Taiwanese rackets "felt a little flimsy." IIRC, Mary Pierce was using the Taiwanese frames when she won Roland Garros.
I have a few earlier Taiwanese frames and ones like in your pics. Great frames. Well built with Fairway grips. It's nice to see ones that are not all beat up.
The Taiwanese frames look to be a period stuck in limbo. Not a "Connors/Evert/Edberg" frame or a "Sampras" frame and not a "Federer" frame. The interest and used market prices kinda reflect that.
