For a pro he's not a good putter, but he can still probably putt better than anybody at your local muni.
I agree that the Aim Point crap should go, and I also think that once you start down that road of alternative grips and all that crap things just tend to get worse.
Rickochet and I will have to agree to disagree about the anchored putting, etc. I don't think they should ever have allowed it. I kind of feel like they should also outlaw anchoring on the forearm like Kuchar does, since in spirit it's the same process.
Putting is a skill. If people want to be good at it, they have to practice it. And, like all skills, some people will be more gifted at it than others, and that's ok. We shouldn't be able to equalize all aspects of putting. It's supposed to be challenging.
