cross-wind practice
I found that x-wind landings properly 'clicked' with me when my instructor doing my tailwheel endorsement/differences took me to a strip that was pretty much full x-wind component and made me approach and fly the length of it then go around.
It seemed like it must have been at least 25kts x-wind, but the exaggerated control inputs needed to do the manouevre finally cemented in my brain/reactions what each of the controls were actually doing.
Waving the hands in the air going through the theory was a pale imitation of this practical demonstration. For me, even doing circuits with a 5kt x-wind was a poor learning experience because the control inputs you need to sense are easily masked by turbulence, wind gradient or other disturbances.
