I am of the school of thought that says you should play in a preflop comfort zone (to some degree). If you are not comfortable playing A2s in ep because you are not comfortable with what to do on the following streets, then fold it. But also try to develop your game to the point that you can loosen up and play it in ep when it's called for. A2s, in the right game, is a long term money maker in any position.

I guess what I'm trying to say is as you get better try to work limping here into your game where appropriate. As you get better you will find your vpip creeping up -- this is common and IMO natural.
