Alyson 2's mouth morphs dont work quite right period.  which is why i am making all new custom expression dials.  and no i dont use any existing dials - its easier for me to just make new ones exactly the way i want them.

the existing Alyson 2 dials can be feathered to get many expressions. but if someone just cranks them to 1.0, they look bad - as do the expression morphs of just about every character ive ever used.
