I love the Rohrig set, not only are the pictures wonderful, but the back is nice too. Some of the imagery is a little beyond me, but it is always beautiful. The mix of old and new is fantastic.
The cards are big, and you need room for a spread. I find that some clients do not like them, because they find them too hard to shuffle, due to their size. Also, there is a fair bit of nudity, and sensuality. Some people have a problem with this.
Personally, I think you should go it. Even if you don't use them as your principle deck, they are beautiful to own.
