committing to hitting

I started playing golf in the 1960s and attempted to follow a Nicklaus style, especially on the greens. Through my teens and 20s I was Nicklaus-like in putting alignment, posture and stroke, I was comfortable with it and didn't have to think "how" on the greens, just "where" and "how much". As the rock-your-shoulders style gained more exposure on the pro tour, I couldn't leave well enough alone and have fooled around with that style a lot with limited success. So, committing to hitting ....

I reviewed the putting disk on the Alignment Golf DVD, it's well done and understandable. In trying to figure out the hitting pattern I want to use, here's where I'm at presently:

a) Angled hinging. (Tried vertical hinging but the reverse roll feel would be too much change too soon, although I may try it later once I become comfortable with a new grip.)

b) The putter grip running down the life line or cup in both hands, the index fingers of both hands extended down the sides and pointing at the base plane line. (I've never been comfortable with the right index finger down the shaft but it makes it easier to hold the grip in the life line and get the right forearm on plane and be able to trace the plane line.)

c) Previewing the length/weight of each desired stroke and then setting the right shoulder so that it will feel natural to extend the right arm fully for each putt. (Lynn made a big point about making sure to fully extend the right arm, otherwise the tendency for the ball to finish right of the target.)

d) Left arm with a consistent bit of bend, left upper arm not really touching the upper chest for most of the stroke. (In the DVD, Lynn talked about extending the left arm but when he was actually putting it appeared to me that he had some bend in the left elbow. Some bend in the left elbow seems right to me because it allows some freedom of movement between the left upper arm and the chest; if the left arm where fully extended downwards, there would be more contact with the chest, creating a potential stroke disruption on longer strokes .... ? Nicklaus clearly had some bend in his left elbow, and Watson makes a big point about maintaining a consistent bend in the left elbow in his short game book.)

Sound like a good start, or .... ? Any "feels-like" tips to seek or avoid .... ? Thanks.
