Honestly I don’t see why more pilots don’t avail themselves of the BasicMed option. It costs WAY less, lasts twice as long, is much easier to use and eliminates exposure to the potential of an overly enthusiastic AME. If the limitations don’t effect you, I do not see the downside.
Regarding non-AME doctors being reticent; a rational discussion and a few minutes research ought to do it. My doctor originally was not on board, but promised to look into it. That was four years ago. He told me the other day he now has about 4 or 5 of us in the area that he does this for.
