I feel playing Ax from EP on a passive table is setting yourself up for trouble.

So you limp with the Ax and get to see the flop. An A hits so now you have top pair and a horribly weak kicker. What now?
Are you going to be the agressor and bet from early position with this pretty weak holding?
Are you going to try and check it down from here, basically adjusting to the table's passiveness?

I think both options are bad play. If you want to play that Ax from EP, I'd prefer raising with it. But my opinion is that by playing Ax you're setting yourself up to be facing tough decisions later on in the hand. Avoid those - fold Ax.
