Greetings,
Jack is a great bloke. When he came across the pond to the US of A ten years back to dive the Andrea Doria we got to spend a few days together out wreck diving. I suspect that even though his presentation is on gear configuration you can probably ask him how different configs work better on different types of dives.
Take advantage of the opportunity you might just find something in there that you can use.
Cheers
