I've seen a lot of equally frustrated users unable to fix huge imbalance problems (worse than 70/30 for me) but I finally stumbled on a solution which I have not seen elsewhere. I went back to my old worn down shoes and cleats and the problem went away. So I carefully cleaned my new shoes, cranked the cleats even tighter, and now I am finally back to 50/50. This won't work for everyone but the other proposed fixes were not working for me.
