Like some others have posted i never got a whole lot of choice either.

By no choice, I mean that over here, when you're needed somewhere and you get the alert klaxon going off, you launch, pretty much regardless of departure WX and regardless of if you have a workable alternate. In the target area, you know the terrain, so if it's undercast, you simply descend through until you can get to some semblance of "below" in order to work the area visually, hopefully with a mile or more horizontal viz.
GA, on the other hand, usually has a choice regarding WX. Prior planning and visual observation minimize the times that someone will get caught in the WX. And few flights are "must go".
