They've never used Bryce or if they have they haven't looked far enough into what Bryce is capable of. I use Rhino, Maya, and Bryce.........so because I use Bryce does that make me a hobbyist?, I don't think so. Another point is that although I use these other "high end" apps Bryce is still may favourite. So they can stick that in their pipes and smoke it.....as my grandmother used to say. Catlin
