Fence-sitting here, but all of them are things of beauty when well delivered. A stiff jab that knocks a head back...an uppercut up the middle that turns the opponent into a bobblehead doll...a left hook smacking into the body.
What about the one where you put your keys in your hand first - the stinger - I didn't see that on the list. No spinning back-fist either. Tsk.
A well-thrown short counter cross that an opponent doesn't see coming. After that a crisp, quick jab is my favorite punch to see.
Let's not forget the "Cup Punch" nothing like a well timed punch to the nuts to get you out of trouble. Watch the JoeCal V Hopkins fight for some nice use of techinque in the throwing and receving of said shot. You also get the joy of watching some quality acting which I think old man Hopkins should consider as his next career move.....
