Im just a tad confused here,where does the "BENT'L /wrist come from,I am lways flat L/wrist,at least I hope I am.

As a Flat Left Wrist Swinger you cannot Roll on Plane unless you use a Wrist Throw to initiate Release. On short Strokes like Chips and Short Pitches you can slightly arch your Left Wrist at the End of your Backstroke.

As for the left arm rotation,I am still having a battle finding a "feel"that reminds my body to rotate my upper arm from shoulder-NOT elbow as this is a point that is breaking my swing down from time to time.

That's because it's not something you should Try to do, it's something that happens as a result of Alignments. Use 10-2-B Grip, a Power Package with a Pitched Right Elbow, Straight Line Delivery Path and Wrist Throw. It will Roll.

Your Right Elbow needs to get closer to your Belt Buckel while your right palm is still facing up and you begin to Uncock as your Right Palm is Facing Up. This Alignment will Snap Roll the #3 Accumulator as the Right Elbow Straightens. It has no choice. You will feel an underhand Pitch motion.

It doesnt matter whether or not my R/ forearm pushes to both arms straight,that can be done with L/forearm roll or upper arm roll (sorry roll should read rotate)but one or the other is causing a faulty stroke.
I hope you can follow my description.....cheers

Don't Confuse Roll with Hinging.

Hinging occurs when the Left Wrist is Flat before, during and After Impact. You're Aligned to produce an Angled Hinge. You want to Align Components in such a way to produce a Horizontal Hinge (Full Roll - See Above)
