In terms of successors at BASSA, I think anyone will have difficulty escaping the shadow of Duncan et al. I would not assume DH will let go of BASSA easily. There are certainly plenty of ex crew who spend their comfortable retirement on other fora poisoning the well.
The fact that BASSA and CC89 have managed (entirely through their own collective actions) render themselves impotent in negotiations with everything delegated upwards to Unite reflects badly on them (just where does all that money go?). Going forward, I expect both separate branches to be dissolved with Unite keeping a firm grip on things.
