I've just spent the last three hours reading previous threads on water treatment methods. (VERY informative)

So now I'm curious - what treatment system(s) are you using now?

I'm most interested in a quick poll. So, I ask everyone to please try to refrain from the long winded response as most everything that needs to be said has been.

Me: I've been using a pur hiker (Katahdine) most recently. Before that was the sweetwater. Before that was a (now defunct) chemical treatment. And now I'm thinking of switching over to Aqua Mira.
