For one it’s alot easily to explain on the ground rather than from a camera view point, if you’re gonna teach skills make that part of the ride and not try to do it after the..if that makes sense.
So find an obstacle, watch them do it, ask them why they did it that way..then explain and show them by pointing what you feel is the right line and why…then demonstrate and watch them do it…..
However it sounds like you use my preferred method of ‘speed is your friend’ and batter your way through it(which doesn’t work quite so well on a chammy 🙁 )
It’s mostly about spotting the exit, lining up for the next section and dealing with the approach..
If anyone reading this has ever followed me, they know i’m making it all up…
