During the planning stage of an IFR flight how to choose the correct SID for your route in an airport with multiple runways and multiple SIDs? and how to predict the runway you will be going to use?
"File what you want, fly what you get."
There's no way to know for sure what clearance ATC will give you until you actually call them. If you're departing from an airport that you know well then you may be able to make an educated guess but that won't help if the winds change, an incident closes a runway, or any number of other things happen to invalidate your assumptions.
For planning purposes, just use the SID that best fits your needs, based on all the information you have available: direction of departure, aircraft type, weather, local procedures etc. But ultimately, you'll have to fly what you get (or what you can negotiate with ATC).
