I think synthetic is the way to go if you're headed to a known wet weather area. If I was going to the Pacific Northwest, Alaska etc. I would give synthetic a serious consideration. I run a down bag for the weight savings and compressibility. I take bivy with me and have never had an moisture on my bag other than from condensation. I'm hunting in Colorado so I would consider that a pretty dry area. I know others on here are generally either diehard synthetic or down.
If I wasn't humping my bag in very far I guess I would consider synthetic but for Colorado high country I wouldn't dream of purchasing a synthetic bag.
