I'm with Sarah, I generally use an Ursack. I have an Ursack Minor too, I quite liked that on the AT last year, but in the PNW am talking about a regular Ursack.
The uncomfortable truth is that, outside of places where bears are habituated, sleeping with your food generally works fine, but I think the responsible thing to do is to ensure that bears don't get our food. An 8 oz Ursack isn't that big a hit.
Hanging (PCT, counter-balance, or "string-it-up-and-hope") has some real disadvantages. My sense is that way too many people do a sort of slap-dash bad job of it, and would be better off (correctly) using an Ursack. Someone mentioned that they find that hanging the food bags is fun; I find it to be somewhat of a time consuming PITA, especially if coming in to camp on the late side (and doing a hang that's really, credibly bear proof). The Ursack is dead easy to use, so I tend to use it.
