I've mounted a few, no particular problems. I like the idea of mounting Phals because they do not like to be repotted and once mounted, they are pretty much set for life. I would not attempt to mount Bulbos because they like to be kept wet. I always put Stanhopeas and Gongoras in baskets so would not attempt mounting them either. Funny about Catts, the unifoliate types seem to take to mounting while the bifoliate varieties don't. The bifoliates don't like repotting much either. I guess they are just harder to get along with.
