I have never tried one, but these have been discussed here before, and the consensus is a big, fat thumbs down. Apparently the stability issue is a big one, and the folks who tried them felt that they were about to slide off the saddle all the time.
You should not be that miserable on a "standard" saddle; it's just a matter of finding the right one for you, which might mean testing quite a few lemons first. And what is a lemon for you (i.e., Terry Butterfly) is lemonade for me (love my b-fly!) You might do better on a Brooks, or on a saddle without a cutout, or a narrower saddle... Or it might be that your bike doesn't fit you well, so no saddle is going to be blissful. Have you had a bike fitting?
Worst case, I would buy a recumbent bike before I'd use a hornless saddle on my upright.
Good luck!
