I used to manage an Original Cookie Company and although I don't know the recipe (since they came in frozen dough form). If the issue is the texture(moist and chewy), try cooking the regular size cookie for 7 minutes on top and bottom shelf (each). Also turn the trays around. This allows for balanced cooking.
I used to manage an Original Cookie Company, too! Which one did you manage? I totally agree with your response to the first post...rotating and slight underbaking are the key.
