Question special

This is the last of a three-part question. Certain subspecialties have divergent opportunities and areas of focus from the specialty overall. Given the limited opportunities for subspecialty electives in medical school, how might students go about figuring out "fit" in these fields? What do you recommend to a student applying to residency programs who is interested in a subspecialty but not the specialty overall, especially if there's a different specialty that the student would enjoy even without subspecializing? (For example, an M3 friend of mine is currently debating between OB/Gyn and gastroenterology, but isn't particularly interested in IM.)
