What specialty were you originally considering? I'm wondering if it is one that is relatively common for FM docs to "specialize" in (e.g. low risk OB, anesthesia, psych, derm) as it might make it easier to make the decision easier if you didn't feel like you were "losing" that specialty entirely. Even if it isn't one with a traditional plus 1 program, is is something that could still include a tailored practice? Not sure where you're located/hoping to practice eventually, but there are programs like Project ECHO (See Arora et al, 2011, NEJM and https://www.echoontario.ca/Join-an-ECHO/Programs)
