RE: landing in crosswind
With the Avistar, you might just try landing normally, actually.....probably have less chance of botching the landing than if you tried the wing-low method and goofed (it is indeed tricky). Only exception would be if it's really windy, and then you'd do well to consider a different landing direction more parallel to the wind. By "normal landing" I mean just adjust heading until the plane no longer drifts (you will be crabbed into the wind). The Avistar is light enough and forgiving enough you might be able to get away with this unless the crosswind factor is very high.
And yeah, Cubs are great for practicing this stuff, as the difference that various techniques make is more obvious with the Cub than with the more "go-where-you-point-it" planes.
Are you having trouble flipping the plane over on crosswind landings or something?
