Camtber and Anaismd, just don't go with the idea big=fellowship. That small program you really like might just be well known and respected by the fellowship program you want to go to! CALL several fellowship programs and ask them!!!!!! You have absolutely NOTHING TO LOSE!! If you can't get a hold of anyone there to answer your question "what are my chances of getting a fellowship if I go to program x?", contact the PD of program x! He may give you biased advice, but then again, he might not.
