Considering you own 3 Pilots and 2 Orpheums, your self-imposed rule seems a bit arbitrary to me.
Ah, but the three Pilots and two Orpheums are all quite different. Two of the Pilots are maple bodies, and one of them is fretless. And the other one is a poplar body, and lives with my girlfriend. The two Orpheums are kinda at opposite ends of the spectrum too, one being a jumbo, and the other an OM.
I think you would really enjoy a Brazilian F312, which is quite different from a F512. And fortunately for you, there are 2 available for sale by LTG members in New York, in case you decide to break your promise to yourself.
I don't doubt the that Brazilian F312 is nice, and would be my pick if I didn't prefer the slimmer nick profile of the single truss rod Guild 12ers. Have you tried one?
