It's probably too late for us now, but ever think that Sam Snead had the right idea with side-saddling? The eyes are on the line as we face the target line, the motion is simpler, and if you hang the putter from your right shoulder, vertical hinging never deviates the clubface from the plane line.
There is always one guy at every club who used to be a yipper and now makes everything side-saddling.
I wish I had learned it as a kid. The long putter is pretty sweet, though.
