Hasselblad portrait lens with good bokeh?

Do any of the common portrait lenses for Hasselblad have good Bokeh? I have a 120 Macro Planar as my current longest lens, and when I recently used it for portrait shooting, the out-of-focus areas were rather unpleasant and harsh in their appearance. I don't have experience with shooting either the 150 or the 180. I don't think I'd want to go to the 250, just because of the physical size of the lens, and the slower maximum aperture. I've been spoiled by the lenses for my 8x10, which have much smoother out-of-focus areas because of their multi-bladed irises.
