thanks for the involved reply!
Yeah, I mean the real reason is that I don't want to be tied down for 7-8 years, and I'm not sure I'll end up doing any research at all. But the latter reason isn't exactly going to be easy to explain with the way i've structured my PS and other materials, which emphasize my commitment to translational research...
but I think I can play up the flexibility advantages of a straight MD program, and the simple fact that it won't really hold me back from the type of research I would be interested in anyway, which like you, doesn't involve basic sciences.
