A John Daly trick

One of my favorite professional golfers is John Daly (a fellow overswinger, and, aside from golf, he just seems like a good guy with a big heart)-- Well, from this great video-lesson (by the quickly-wise golfer John Richardson, who I'm glad to have stumbled upon) I learned a John Daly trick for a lighter swing: Swing a few times with just the forward-hand (left if you're right-handed). Got a couple good blisters pretty quick from that, but blisters only make you stronger, right?, and it does help a lot for my pitching/chipping (strengthening and memory). I noticed Daly seems to use it for more than pitching too-- good stuff.
