As far as your wrist discomfort, and the turning you may really want to concentrate on your posture more. I know you said that you were correcting your posture for comfort, but what you really need to concentrate on is putting weight on your feet, not so much on your butt either. Your legs are the strongest muscles in your body after all so go ahead and use them. Along with this you'll want to use your knees more to grip the side of the tank, then use your hips to turn the bike at slower speeds to dodge those pot holes a a little easier. Putting the weight on your legs is why it was more comfortable to stretch when you took your hands off the controls briefly. Just remember, weight on the legs and light on the controls, and as a by product you'll develop better throttle and braking inputs.
I do believe i took that picture.
Bike is lookin' nice there! Hope you are having some fun with it this summer.
