Probe those ribs as suggested. They will come out better for you. I used to go by looks and feel, until Smokin gave me a few cooking lessons. They turn out consistently better now.
I brine my pork loins all the time now...Smokin again. They come out more moist, but more importantly, more flavorful. Seems today's pork loins are much leaner and less flavorful than those my folks used to cook.
