Training the pivot.

[Toolish]

I have fought a flip for a long time...longer than I have known what a flip is.

I think it is tied into my pivot though. I don't flip on shorter shots, but when I get to full shots my pivot stalls and i run out of right arm as my right shoulder stops turning down and around through the ball. Therefore I flip it.

How can I train my pivot to keep going better? How does a problem like this tie into hand controlled pivot vs pivot controlled hands. I sense all the problem with my hands, but I think the pivot is the issue.
