About all I can say is as follows:

1) It will NOT be what you expected
2) If you are in a fair fight, your tactics are unsound
3) Win, Lose, or Draw (unlikely), everyone is going to be sore at least if not truly injured.
4) Many jurisdictions have an offense called Mutual Combat (or words to that effect.) Plan on spending the night (or longer) in the can.

I have often said the best fighting technique involves one's feet. Place one foot in front of the other, and repeat. Just as fast as one can...
