I've been playing a Fylde 12-string (Falstaff) as my main guitar for about fifteen years (after various Fylde 6-strings and citterns/bouzoukis). I keep a capo on the second fret and use a dropped-D tuning from there. I can capo all the way up the neck with minimal re-tuning, and the reduced string tension makes it really easy to play without losing too much resonance.
On visits to Australia I have played John Warner's Maton 12-string and my niece's Martin 12-string (don't know the model) - both great-sounding guitars, but I'd still prefer my Fylde.
