I've thought of this topic a lot myself. I think to be a pro (not A+, A, B, but pro), you need to have BOTH incredible talent, and the work ethic to go with it. There are a lot of A+, A players that can have the same, if not a better, work ethic than most pros, but you don't have the uncanny talent the pros possess, you'll be limited...no matter how hard and how much practice you put in.
I think the main question is, what exactly is the "talent" that distinguishes the pros between the rest? Is it sound mechanics? Is it speed control? Is it position play? Is it mental toughness in pressure situations? I think the "talent" that truly separates the men from the boys is pure shot making and pocketing skills. To an extent, decent shot making can be learned, but the outstanding shot making of the pros cannot be learned. It's either you have it, or you don't. The rest of the skills I mentioned above can be learned and engrained through time and practice. But shot making is different. That is why the likes of Buddy Hall and Earl Strickland can run a rack of 9ball only days after first picking up a cue...because they've always had that uncanny shot making ability even before they took their first ever pool shot. Anyone disagree?
