I am throwing right handed backhand and the dog legs right come naturally. But when I try to correct for dogleg left I get this double Heizer thing going where the disc ultimately goes right in an S move
Well, consider yourself lucky; most people have to work to get that. Hell, I still suck at them most of the time. You must be using a really understable disc. Also, I imagine you're performing a sweeping motion with your arm instead of a "lawn mower pull" which is probably contributing to your arm being sore.
