It's on a DVD and I don't know how to capture the frames. It's not a gross difference in positions and would be very hard to see in pics, I would say. I can try to explain it. The farther down the shaft you place your trail hand, the tighter the angle it makes. Now, does an inch make a real difference? I dunno. There also seems to be a change in angle simply due to the different way the hand sits when using an overlap.
Overall, it looks good on paper. I'm not ready to change at this point.
