Kev,how are mate,I hope you are well,I have been watching this post and Im a tad concerned you are getting bogged down with possibly "too much info",
re youre comment on the hip motion and hands take-away etc,I would be more inclined to concentrate on the forearm takeaway,getting that right will bring a few other aspects "along for a ride",ie hips,and pivot.
If you developed a good solid takeaway procedure with R/forearm,guess what,the pivot will come along without you trying and will only do what your plane will allow it to do.
In essence,forget pivot,and hands to a certain degree as they will follow the forearm takeaway,as a matter of interest are you fanning on the takeaway.
cheers B
