I'm more experienced with H/L. Of course, A A 2 3 is a huge hand because you have the low and the low straight possibility.
If I have an ace and a good low card, I'll usually try to see the flop in the event that I can complete my low.
I also like high pairs and any four cards which can be used to form the same straight. For example, 8, 10, J, Q or 4, 6, 7, 9, etc.
Two pairs of suited cards (e.g. 2 :s 3 :s J :c 6 :c) are a nice touch, but I wouldn't count on it being the winning hand unless there's more to it.
But that's just me.
