I'll give you a general answer. The oil sands industry deals with huge amounts of materials being moved, and they have to be moved fast in a certain way. They go mainly with technologies that can deal with huge amounts of materials. They don't want to have any kinks in the operation that would delay them. Sometimes they are very careful about what new technologies they apply. They have to fit it in with this general principle of dealing with hundreds of millions of tonnes moving in all directions. That's just my opinion.
