As Lucy said....some do better in certain areas than others, and some concentrate on a particular class of iris, so it would be awfully hard for me to pick one from the crowd. And, as Tom stated so well....everything introduced today was built on the foundations of what came before....and that will continue...so, in effect, the "whole", is greater than the sum of it's parts......and every part was, is, and will be, essential in producing the irises of the future.
