Well, this very well may be where ODLH has to go to Bully fighting. Can't really say anything else on the subject until I see training.
PBF has a great defense, but as mentioned many times he usually opts out of throwing combos. If ODLH can keep up the pressure (he's only 33) he will definately be able to make short work of PBF. And to answer your question, no we no idea how much is left in the tank.
