Mark,

You're a way better pilot than me, but the only advise I can give you is to practice only with right rolling maneuvers.
I have the same problem, in rolling circles I prefer a right turn when rolling left and a left turn when rolling right. So I practice a lot on the other directions. Very frustrating in the beginning when it doesn't look so good but it gets better all the time. I'm not saying both directions are now going very well but it's getting better and better.
( My club-mates say I'm crazy when I'm doing flights of 10 min. constantly flying rolling circles!)
But I'm not a competition flyer like you, so I wondering if I'm the right person to give you advise...
