Pretty much what the title says -- I'm planning on applying CP-only, but there's very little CP exposure at my school other than a quick lab tour during our path elective, and my interest developed too late to set up a longer CP-only elective. I have two pathology letters, but they're from faculty who practice AP. I had a meeting with a clinical pathologist where we talked about my interest in CP, but he wasn't willing to write me a recommendation since we haven't worked together. Basically I want to know how aggressively I should pursue a letter from a clinical pathologist at this point, or if my two pathology letters from AP folks will likely suffice.
