Jn, You will get more ICU and CCU immersion that you ever cared to have as an intern even in ORTHO. AND if you take it as a fourth year in the fall you will likely forget it (much less how many milligrams are in one tablet of tylenol) or if you take it in the spring you will be ready to strangle yourself, because you realize that you have hardcore senioritis, wish you were taking that "medical art" elective and don't learn the CCU/ICU stuff anyway because you have already matched. Just my two cents. Radiology (especially musculoskeletal if you can work it, not mammography) is beneficial, ER is very handy, Rheum is probably a good one, Physical medicine, Pathology is also good if you are looking for electives that might help and don't kick your butt too bad.
