BerntR,
You are right. The double overlap is the best way to hold the club. I have been trying it out on the range past month and it feels superior to the interlock.
I can feel and monitor PP#1 much better.
PP#2 feels more secure. modifications I made was just slightly smaller diameter grip size on my clubs, nontapered grip. and hold the club with strong left hand grip. The club sits way more into my fingers with tightest pressure over the little finger and progressive less toward the ring finger and middle finger. The left index finger sits on top of the grip with no pressure on the grip.
