Yeah, I tend to cook a packer in the same size range as the others, no I don't trim off all the fat.
Like Smokin' was pointing out...a person will learn a system that will work for him and his smoker, that will determine how he goes about preparing and cooking the product. My preparation may not work for your system and so forth.
Key is practicing, keeping good notes and as Smokin' would say,"change one thing at a time".
It also helps to know what your wanting/hoping to turn in. I know what I want, it's just hard to get that dang ole tuff piece of meat to cooperate...LOL!
