I applied to all MD/PhD + MD. I will have strong LORs. I got my BS and MS in Microbiology of Univ. of Hawaii. 2 letters are coming from profs that taught me undergrad and grad, and were both on my thesis committee. 1 letter is from neurosurgeon I shadowed. 1 letter is from my PI in undergrad and grad, who was a prof and thesis committee chair. 1 letter is from current PI, who is MD/MS doing cancer research. BIG QUESTION: should I be asking them to write 2 letters - 1 for MD and 1 for MD/PhD???
