I find the old leather covered Unicanitors very comfortable. I know they look like a ss hatchets, but that isn't quite the case. I don't know how different the shape is on the BMX models however. And let's be clear, all of the saddles pictured so far have been the BMX model.
For those of you scoffing at it from a photo, an opinion of a saddle is usually better formed after actually sitting on it. Until you've at least done that, your commentary is useless.
