Birdie,

A reverse pivot is not so much a spine angle issue, but a malfunctioning hip turn. The weight shift to the rear leg is usually accomplished by the turning of the hips. A faulty hip turn leaves weight, or places or the load on the forward leg and the weight is "reverse" shifted to the back leg on the downstroke.

I can agree with that. It is the cause....

(....of a spine that tilts towards the target in the Backstroke...)

Question: are there or have there ever been any GREAT or even VERY GOOD players with a reverse-tilted spine at Impact?

I would crap myself right here right now if there were.

Not to say you can't get to a rearward tilted spine at Impact with a "tripod" type pivot....

If it works better for most people for every club and every shot is the real question I guess.

Believe me I don't like a MASSIVE sway either....you must have A center as Lynn said.

Choose what works best for yourself....

I don't know that anyone has ever HAD a beef (but who would I be talking about...) or could/would ever HAVE a beef with someone doing the "tripod" if it worked better for them.

Really that should go for anything that works for anyone.
