HU usefull stats to profile players?

[Chairman Wood]

I apologize if this has been asked before. I'm a SS poster so I don't read here on a regular basis. When playing HU or 3-handed I am well aware that the usefullness of stats starts to diminish and it becomes much more important to have "real reads." At least, that is my opinion. However, I wanted to ask those of you who play a lot HU and ultra shorthanded, what stats, if any, from PT to be used on a HUD do you find usefull and why? Do stats in anyway take on a different meaning here than as in a 6 max game?
