Some of these guys have pretty amazing hand-eye. I think there's another guy called "Hammer" something-or-other.....he's on TGC sometimes. Very good. I wonder how much of that coordination can be learned.
As for the baseball swing...
It's actually kinda like a dynamic George Hibbard..............
...
I used to work at a range tho..........u can actually get "stripin" em surprisingly good walking into it like that.
Back and fourth back and fourth.....I used to just walk the range and do this. More or less off concrete.
i.e.
In a dome with only a real thin green so-called "turf" (which was closer to a thin, felt-like carpet).........and after I busted my 5 iron- with rental clubs only of course.
No wonder my shoulder is always sore though.......I would never think of doing that now. When you're smokin em it's too fun though.
