Mike, if you know where to buy a plant of Flying Saucer, I'd be happy to keep its genes in existence.
I have Bernicker and Maher and enjoy both, and both are quite dwarf for me. I'd love anotehr dwarf.
I've seen mossmans nearer the 5kg mark. I'm affraid of them when they reach that size. I picked up a 3kg whopper once and it just never ripened, staying grey on the inside for over a month...
