In like 99% of circumstances the attendings at your school are going to write garbage stockletters that are meaningless. An amazing student with a bunch of publications applied to my program. Literally the attending author on their papers stocklettered them. They did fine but I still found it attrocious. The only times I can recall an attending actually writing a real letter were for students who didn't match where the attending tried to describe the students turn around and what they had been up to.
Where am I going with this - letters are merely a checkmark box on the path to residency. Because the letters are universally such garbage - the end result is no one reads them. They don't set you apart or improve your chances. There is no "power person" you can get to write your letter because no one in Iowa is going to know who is good in NY etc.
Ask some people. Fulfill the requirement. Move on. This isn't like MD/DO residencies where letters open doors.
