last 150k hands (i.e. July and August and a little bit of June - basically since i moved up to 100nl)
AA 702 times, win 92%, w$wsd 81.53, and it's earned me $10.63/hand.
I like aces.
also, cos you may find this interesting. My hand profits over that reasonable sample - in order:
AA
KK
QQ
AK0
AKs (better rate/hand than AKo, but less frequent)
JJ
99
TT
88
AJo
33
77
55

22, 66, 44 are all losing over the sample - I blame playing too hard from EP and liking low sets too much heavily multi-way...

contrast with my biggest loser, T5o which has on average lost me $0.24 each of the 1400 times i got it.
