I have a rodagon 60mm WA that I use routinely, it replaced a 80mm componon-s. It is a very good lens, and is very sharp with prints that I have made with it. Barry Thornton's book The edge of darkness has a chapter comparing enlarging lenses and sharpness from them, and the WA lenses do very well in his tests too.
This lens is really designed so that you can get more magnification if you max out your column height routinely. You wont save that much time on exposures and if you work close to the paper your gonna make it tough to dodge and burn areas. If you routinely have to crop that much you may want to adjust the cropping in camera and have a good full negative to use for printing.
