I have a "chin strengthener". Also known as a "soul patch" I guess. I had a full beard a number of years ago, but was persuaded to shave it off when people saw pictures of how I looked without it. I think I look best how it is now, a small patch on the chin, shaved smooth elsewhere, but I do not enjoy shaving. My skin gets irritated easily and it's such a time consuming task.
A gripe I have about full beards, though. If you have one, please take some time each week to groom it. A little trimming goes a long way to taking it from "bird's nest" to "ooh, nice beard".
