Legends, in comparison with ala's, have nothing in common at all. Materials, design, logo's and production ways are all different. Its the same, if someone would try to sue company that produces plazma TV, because their oldstyle TV looks similar, but in all other ways is different.
And my pro-bono lawyer says its so ;-)
About morality of this... phlox them. They are the ones not producing ala's, so its their fault! Dont think its easy or cheap, to make the fins. Its not.

About performance of Legends, its not known yet, as I havent tried all the materials available, but I'm confident to find the best solutions possible. This much I'm sure of, as I'm the one that will be making them, and I know what I want from a fin. On this photo I used two separate materials, one of them is very close if not already perfect, the other is not satisfactory. Its what testings are all about.
