I agree with the principle here, but it would seem that straightening out this angle would tend to put the club in a more "toe down" position at impact than at address, wouldn’t it?
Maybe Greg will jump in here, too. I believe he’s described a sort of "hammering down" thought while releasing his wrist cock. It would seem that if you completely release your wrist cock (true cocking....up and down..not swatting) that this angle would be tending to completely straighten out and put you "toe down" especially if your hands return to impact slightly higher than address. Maybe you could elaborate a bit.
