Tiger Woods stated in "How I Play Golf" that he grips the putter under the heel pad of the left hand.

"under the butt of the left hand", he says??? I think it's less in the palm but not under the heel.

My golf buddy grips his putter like he grips all other clubs, and he's a decent player, so I guess it up to you. But I think in the palm of the left hand is classic. You can have your forearms on plane and the back of the left hand corresponding(?) with the putterface.
