I've tried everything on the list (plus a couple that aren't) except for the ankle (don't use them, I stand up too much), SOB (I don't like the idea of a big piece of steel lay across my spine) and thigh.
Each of the other options really depend on what you are wearing, what you are carrying and what you will be doing. Wearing a shirt and tie minus the jacket during hot weather (I live in the South, nobody wears a suit coat during the summer unless absolutely necessary and even the, not for one second longer than absolutely necessary) pretty much means I either carry off the body or in the pocket. ON the other hand, if I'm wearing a leather bomber style jacket, I prefer to use a shoulder rig over carrying on the hip or IWB behind the hipbone. A longer, light jacket give me a chance to carry IWB at 4 O'clock while a heavier jacket like a barn jacket or a below the hip bone length winter coat lets me carry outside the waist band at 3 or 4 o'clock.
