hi john
this is the first time replying to a topic , everyone seems to have some great ideas on what would be valuable on a tutorial disc, rather than every thing on one disc , might it be progressive , you know kind of like maintenace ,beginners , intermidiate etc you get the picture . loads of work im sure. good luck on it!
i do have a question on the long handles used in the paola ceresa video sent in by mario,are they something most rev flyers are inclined to use and how do they change flight control compared to the handles supplied with the b-series.... more/less brake or what? 
Handle length is a factor of both local conditions as much as personal comfort.
The higher the wind, or the more precision you want to fly with = shorter handles
Slack and trick flying, very low wind, or short lines in tough turbulence = longer throw handle lengths.
I carry several lengths from 10 inches (measured across the gap, NOT across the back parameter of the curve), 12's, two pairs of 13-1/2s, a set of 15's and 17 inchers, only the 13-1/2 ones are stainless steel. All the others are wrapped graphite.
I also have a favorite pair made from grade five titanium tubes with custom grips. They are both extremely light in weight and durable. They allow you to fly light weight kites whilst standing on just one foot,... effortless and enjoyable for extended periods of time.
They are also advantageous for instructions, 'cause they force newbies to make tiny little adjustments. A big move dumps all the air regardless of flight orientation on the kite.
Say you want to do an axel, you just flick one thumb forward while pulling the other handle back sharply. The kite rotates around nicely, almost all by itself. In the land of no-wind you will be watching without this increased leverage.
The other day I was out with 120 foot lines on ten inch handles and a vented B-Series. You'd swear it wasn't even me on the handles! Winds were gusting to the middle twenties, so why tire out myself. I sat in lawn chair and relaxed while practicing my "own a hover".
