HUD Stats

What stats do you use for heads up? I am not talking about the full person SNGs when it gets to heads up...by then the blinds are high and all about being the most aggressive. I am talking about the matches where it is heads up from the start.

Here are the stats I am using right now:

VP$IP
PFR
Fold to CB
# Hands
Total aggression postflop
Aggression frequency
Went to Showdown
Won at Showdown
-----------------------------------
Bet Flop
Bet Turn
Bet River
Fold Flop
Fold Turn
Fold River

I don't show all the bets and folds by street for a full table, but with heads up you have a lot more space to display additional stats. Any additional ones I should be using?

I also like to look at my stats to make sure I am raising enough preflop, not folding too much on the flop, etc. Is there a range you should be in for things like VP$IP and PFR in a heads up environment. I am thinking VP$IP should be fairly high (75%) and PFR around 30%?
