So, I spoke with a grad professor at my school and mentioned that I was interested in medical SLP and what not. When we got talking, he said that at one point, he worked at a hospital and was responsible for hiring SLPs. He said that the most important aspect of an applicant's resume/experience was their clinical work (where they were placed, what they learned, what clients they were exposed to, etc.) He said that so many grad students freak out when they get Bs in classes but the real learning takes place in clinical experiences, so your performance there is going to be more important.
Keep in mind what coursework you find more appealing, but if you are concerned about what holds more weight in the job search, this particular professor said that, in his experience, clinical work trumps coursework/grades.
Hope that helps a bit
