FWIW, I've yet to find a so-called Player's Cavity that was easier to hit than a quality Blade. They are a half-a$ compromise between two different design concepts, and (to me) provide half-a$ results. I prefer, and play Hogan blades, but I would much rather play a full cavity back than one of the scalloped pseudo cavities. As Monty said, "I suppose they have a sweet spot, but I'm damned if I can find them..."
Subjective, but just my $00.02.
