Prince racquets always give me the feeling that they're good, but not stellar. I know I'll always have my eye out for something better. And the open ports are an acquired taste: it does in fact open up the sweet spot quite a bit, but definitely at the expense of feel.
In other news, Plat 99 officially eliminated. If I'm entering a serving contest, though, it would be the first racquet I'd reach for. Just far more in tune with the 94, by comparison.
