Most of the time, if I get stereo tracks that I know should be mono, I just split into mono and delete the original stereo and one of the monos. One thing I like about Pro Tools is that when creating a new audio track it always defaults to mono, so you have to make an extra click to select stereo. Most things I record from external sources are almost always going to be mono, other than stereo outputs from a synth.
