I love the butt-out tool. That's the first thing I do. Once I get the belly opened up, I take my knife and rip it up the rib cage just beside the sternum as far as I can go, cut the esophagus and trachea, grab it and pull down as I free the other organs with my knife. Once the vitals are free I just pull out the rest by the trachea only cutting as needed. Works like a charm. I leave the bladder in the animal as I see no reason to risk puncturing it.
