Hangboards are for max strength not AE work as in the Metolious workouts, do that kind of stuff on a wall.
Check the Simpson article, good workout that one.
Try doing some repeaters, add enough weight so that you can't hang for more than 10 secs, 5 is maybe better, then hang for as long as you can, rest for 5 secs, hang again, rest 5 secs, repeat for 5 hangs, rest for 2 minutes and change grips. Go through a few 2 finger combinations and small, med edge, pinch etc. Rest for 15-20 mins and repeat the whole set if you can. Pretty intense but great for building finger strength.
Try to do as much one arm work as you can, maybe try seting up a pulley system to take some weight off so you can hang from some of the edges etc.
One arm lock offs, uneven grip pullups, etc.
Plenty of stuff to keep you going for a while and whenever it starts to get too easy then just drop an arm or add some weight. Remember to rest enough in between sessions to recover properly.
