I don't know about all that. The thing I look for personally is the last 5 to 3 feet, I don't know what you call it, I know it when I see it, and I don't care if it hooks 3 boards or 10 boards, or 15 boards, but its that little jump your ball makes right before it hits the pins, it carries every time.
