[12 piece bucket]

Now Kevin this is where i disagree with you cause the scientists are confirming stuff
Now NMGolfer was going on about hand path and the radius deal shortening etc etc a while back and the other one mandrin is now blowing his trumpet about vertical thrust adding speed etc etc
But you know the DS already had this figured out although it dont come directly from either parts of the body these guys talk about

I think Mr. K got that vertical thrust deal . . . pivot lag . . . . the spine is a component of the pivot . . . hips forward and up for the biggest radius . . . swing from the feets.
