After reading most of these posts, HarryC in my opinion has it right.

I practice using rudder only in normal flight with my sport planes. Practicing rudder only is not the most fun in the world, it's like being forced to practice the piano as a kid. I mention using the rudder because I don't use it on crosswind landings.

I love flying in the wind and I love crosswind landings. 20 MPH is my max. 20 MPH is a hefty smack in the face. On approach (unless my fingers do it subconsciously) in a crosswind I use ailerons only. The airplane crabs in. I DO NOT use rudder. I am conscious of using rudder right at touchdown and rolling out.

I've experimented using rudder on approach and I nearly crash every time.
