LOL. Luke, not pointing a finger or raising an eyebrow at you.
After I read the question and his follow up question, I asked myself what I would normally look for if I had to move off of my NRP, and my thought process left me with those questions.
The ball choices he asked about are all legit possibilities depending on the local situation. I don't know either, and I wondered if he had considered whether it was more cover driven or core driven.
In my case, I always have to watch my ball through the pins to decide what part of the motion I need to change to keep the carry fairy in the house.
Cheers!
