came across this little FTR thread

Fnord says that if you hold As5s then you will get these flops, and lists them into categories of ; Once in a lifetime; Longshots; Strong but uncommon; and Common.
Not really relevant but its an interesting read, especially the flops he says are common....
Xs Xs X Draw to a nut flush (careful if the board pairs up.)
Ax X X Top pair, no kicker also trouble
5x X X If the ace comes on the turn or river you can sometimes beat up top pair strong kicker with your two pair. Somewhat safer flop than the pair of Aces because you have a better idea of where you stand.
2x 3x X Gutshot straight draw, several variations
2x 3x 5x Pair with a gutshot draw to the sucker straight. Even worse if single or two suited without spades.
and then says
Note: A6s - A9s can't flop bicycle straights nor gutshot straight draws, hence are weaker hands than A2s - A5s since the difference in kickers is trivial
