Shaved head here also...advanced MPB -- way worse than Statham -- so not a ton of options hair-wise and I tend to keep it completely (and perpetually) smooth. 

A little less than 6 weeks in on the beard at the moment, but I share some of your concerns about the big beard/bald head thing. Time will tell I guess. In the meantime, I've been carving kind of a hook from the sideburns over the ears....sort of a "hanging beard" effect. Seems to work for now, but not sure how it'll fly as the beard gets bigger.
