1. Heel moves definitely, same with the DDT (The Whelp on Steamboat's head after Jake introduced himself to the Dragon on the Concrete floor says it all)
2. Spear is good for one thing in a real fight: follow through into a full mount for a Ground and Pound or submission(average fighter isn't very knowledgable on the Guard). Principle problem with a Spear is that it can be contered into a DDT, a Simple Kneelift, a Sidestep, or A Guillotine Choke (Front Facelock with bodyscissors, Stretch and welcome to a whole new meaning of pain).
3. Well placed Headbutt, unless the guy brings his head down. Nose and Jaw=good deal of damage to them. Forehead=possibility of knocking yourself out.
4. Tongan Death Grip. You laugh, but think about it: Great deal of pressure on the throat area.
5. I think Tank Abbott used a punch for a finisher, too.
6. No one, however, can argue with the greatest Finisher to use in a real fight...
