Scott, I think that is close to the way to describe it. As for my grip, I've been struggling with it for a while now. Haven't been able to solve the problem with my local driller and have turned to some knowledgeable people here on BR for help. It makes it difficult for them to help me as much and fast on line as it would be in person, because they can't see my hand, but I think they and I are slowly getting there.....
JohnP's advice on Ron's tips is always good. I am sure you've visited there.
It's a "feel" thing I bet. I know when I stay more under/forward roll I feel more pressure on my ring finger....come around side for more skid and side roll more pressure on index finger. The ring finger thing is a big John Jowdy principle. He likes the ring finger lead.
Brick--Do you knuckle with your thumb? Some knuckle and don't even know it.
