There's lots. But whatever you do just make sure you have at least ONE technique! There's nothing worse than watching a poor old candidate who has no idea on wind allowance and makes a botch of it....
I personally use 2 times the drift outbound in the holding pattern, and 1sec per knot
per minute for approach in a headwind, 1/2 second for tailwinds. Works reasonably well.
Make sure you pic something that you UNDERSTAND and even more importantly can APPLY it!
