I have a way of adjusting my ailerons. it may be a bit silly but it works for me. I set minimum travel and I mean very minimum. Then I fly it around on a maiden and if all is going well after its trimmed, I do a simple aileron type roll. If the plane corkscrews, then I don't have enough and I keep adding more each flight until its a nice smooth roll and there I have it. Not need for dual rates on it after that. I always dial in -10% expo but that is as far as I go . I just don't like expo because it makes the controls feel sloppy to me.
