You'll get some different answers here, but for me, putting is wholly individualistic...just look at some of the funky styles out there...the trick is to roll the ball consistenly straight, ideally with your head even or slightly behind the ball placement, eyes over the target line (although some keep their eyes on the inside...again, individual choice)...at impact hands should lead and be slightly ahead of the ball for a smooth roll...everything else is pretty much up to you...get something that feels comfortable and balanced that you can repeat, then groove it...
