You don't need to produce first or second harmonic of those F#s, either. I had an AB1 I keep with F# tuning, and it works just fine for 100% of the things I do with it (recording, loud metal band, and sit-ins with various other ensembles). On my Fractal presets, I'm pretty aggressively rolling off under 80Hz anyway, but the F# is still awesome to have.
