This is not a pole, this is an opinion'd answer-forum.
What is your favourite fist? Clearly there is not a 'better' fist, because they must all work in combination and harmony, but does anyone have any favourites?

Pi Quan "Splitting Fist" - METAL!
Zuan Quan "Drilling Fist" - WATER!
Beng Quan "Crushing Fist" - WOOD!
Pao Quan "Pounding Fist" - FIRE!
Heng Quan "Crossing Fist" - EARTH!
- HART! (Wuji...sorry, I was thinking of the "Captain Planet" theme song. Does anyone remember that?)

So yes - what is your favourite Xing Yi fist?
