Brian,

A lot depends on the airframe and how it responds to control input. Some have a very strong rudder and can even roll from rudder input only. Others is much less and its useful in making coordinated (or deliberately uncoordinated) turns but the ailerons will roll the plane and elevator applied to initiate a turn.

Keep the mode you're most comfortable with and just get used to each plane responding to whatever control surfaces it possesses.

Regards,

Clay
