If you're back to bare brickwork, you could, technically, use the one coat stuff. If you do you'll probably regret it. This stuff is particularly unforgiving of poor technique.
Bonding is the right stuff for the job. rake out the joints a bit before you apply it, to give it a key. As long as you make sure you have removed all the loose stuff from the wall first, you shouldn't need the PVA. It's worth washing it down, thouroughly with water, to remove all traces of dust, then apply the Bonding about 10mm thick.
Bonding, is not intended to give a finish though. You'll still have to go over it again with finish (at about 2-3mm thick). Although this means that you are going over the whole job twice, it's still easier than using the one coat stuff.
