The canopy collapse question is a good one, and it's one of the many questions I am thinking of in the category of "one right way". There is probably more than one right way to collapse a canopy. What method is best depends on a bunch of things, including the type of canopy, the prevailing winds at the DZ, etc. The question of what is the BEST way will also depend. Maybe your landing area is all sand, so your big concern is longevity of the canopies. Every DZO will make these decisions for themselves. My plan for the new SIM is to treat questions like this as follows:
1. Explain WHY you need one right way (in this case: the canopy can drag you, and that's bad)
2. Give an example of one right way (I teach drop one toggle and use both hands to pull hand over hand on the other steering LINE, mostly because it's foolproof and they already have the toggles in their hands)
3. Say that there is more than one right way, and tell the skydiver to ask their USPA instructor about the most appropriate method to use at their drop zone.
The advantage of this approach is that it allows you to teach whatever works for you, but reminds instructors that they have to teach SOMETHING. It also means that you can tell the student to go read that section of the SIM, and if they don't ask about how to collapse the canopy afterward, you know something useful about how likely that student is to actually read things.
Things like mnemonics, for gear checks and canopy checks, are another good example of questions that I plan to treat with this "one right way" approach.
