I don't know as much about golf as you, but I have the urge to object to "finesse" being used to describe being able to hit a smaller sweetspot. Thinking of tennis, I would say finesse should be used to describe being able to vary your swing, putting "english" on the ball, soft tap dink shots, etc.
pros are going to be better with any type of equipment, and they're going to be better at finesse, but doesn't a bigger sweet spot allow amateurs to play with more finesse than they could otherwise? it means more reliably being able to fade, draw, etc. rather than slice and hook, and it means more people can enjoy the game.
By "finesse" I just mean that the sweet spot is to small to consistently hit with a full powered swing, so by doing that, you're taking a huge risk. That's the way it was in the 70's, but it's just not that way any longer. The idea is that there needs to be a tradeoff between power and accuracy.
It's like absolute night and day. It used to be a combination of balance and power. Now it's just brute force. The way Bryson is playing just isn't possible with a persimmon.
