Class III vs. Class II medical

If you don't need a class II, stay with a class III. If for some
reason you fail any part of the class II additional checks (I don't
know what they are off hand) you have failed a class III and will
have to appeal it to the FAA. that could cost you any future
medicals.

Are you sure about this? I recently failed part of the class II
additional checks (my eyes have zero depth perception) and had to ask
for a waiver. It was thankfully granted, but I assumed that my existing
class III medical was still valid while this was under review. That's
what the doc told me anyway.
