I recently at our local mastergrower, Hans Christiansen, in Fredensborg, saw a division of MM in bloom. The flowers might not have been the mega-biggest, I've seen, though they could in no way be called small. But the proportions of the flowers, its colours and their interplay, made it in my eyes as close to perfection as can be.
In this sense, one can only second Fabrice. So many parameters can be the foundation for a decision like kiwi's - apart from the latest fads in breeding and judging, and the breedability of the plants; one also has to reckon with one's personal, aesthetic preferences....and here the old adage comes true: it's all in the eyes of the beholder. As Fabrice's example with some of the OZ-clones amply illustrates: what to one person might be seen as a huge step forward, might for another be a caricature!
Maybe, here is yet another paramter at stake - as Sam of Orhcid Inn probably would put it: here you buy a piece of history!
Kind regards,
Jens
