My aresonal I have a Weber 22" kettle, a 22.5" Smokey Mountain, a Pitboss Vertical Smoker and a Monment gas grill. For me nothing replaces charcoal, my WSM is my favorite.
Favorite cuts are between Ribeye - although I prefer it as a roast these days. If I do cut myself a steak I cut off of the 8th rub bone (small side) the width of a single rib.
A few of my other favorite pieces are depending on your region here in the midwest call them Coulottes, also more commonly known as Picana or Top Sirploin Caps. They are great meat for almost anything or cooking whole and making sanwiches or fajitas. Another piece I like is the Chuck Shoulder Clod, if you smoke a whole ones we call it a poor mans brisket.
