Ya man heavy swingweights are the way to go.
BTW- shootin4par....
I'd say weighted clubs amplify Centrifugal Force (and it's feels), the setting of the club (and cocking of the left wrist), the swiveling of the left forearm......increases lag and drag, etc....amplifies and helps with all that Swinger stuff (and hence alerts you to what those things FEEL LIKE- so you notice those feelings more, and the importance of the mechanics that create those feelings).
Basically, a weighted club is too heavy to throw around and throw AWAY (i.e. casting/loss of lag).....you have to start the club on the right plane let the club swing itself......or should I say, let Centrifugal Force swing the club.
Prolly should be careful not to let your backswing get too long with it though (although I guess a long backswing suits some golfers....like Daly or Mickelson or w/e....just monitor it tho and see what's for you....keep the constant tug of Extensor Action and let that determine your swing length).
Brian (In Confessions of a Former Flipper) talked about "doing some work" with your backswing.....getting some momentum going with it so that when you get to the top of your swing, and then CHANGE DIRECTIONS, you get that extra resistance from the club still wanting to go the direction your backswing was going.....the shaft stresses against your left thumb/cocked left wrist (and hopefully in the plane of your Left Forearm Flying Wedge- i.e. left wrist-cocking is IN-LINE with your left arm) and you'll likely get more lag.
"Change of directions shaft loading" (or something like that).....if you can see what I'm getting at.
Weighted clubs are good for pure Swingers (Centrifugal Force...i.e. no Hitters or punch shots or w/e)......be careful not to go at it too hard with one of those things tho.....my friend messed up his elbow with one.
Start slow, stay smooth, feel CF working, and you'll be fine.
