MG,

It IS an option!
Spine parallel to the ground(at the neck). Left shoulder 'rocks straight at the ball of your left foot, then back up(vertically), which has hands moving straight back and through, and hence putter.

So, it is an option,
Cheers

For me, it has just never been a natural thing. I used to try Pelz' method and it ruined my putting. I still am nowhere close to the putter I used to be and I am confident it is because I messed with the straight back and through stroke. I just don't see good players do it.
