We have the constant crosswind too, One thing we found that helps the guys that fly with just one stick, is to have them try to fly straight down the runway heading using only the rudder to stay on course. You can do this in heavy traffic because you can do it at any altitude you deem neccessary for safety. With the strong crosswind that we have there are only two ways to achieve this. You either use the ailerons & come straight down the runway heading at a strange looking lean into the crosswind, or you can use the rudder to stay on your heading & come right down the runway nice & straight & flat!! It is very easy to do & a good simple way to get used to flying with both sticks.
