In the bonding vs filler chat, that was one lesson I learned very quickly when labouring. I had to do a few chases and holes as the plasterers were often busy doing actual plastering.
What @Airhead says about trying to get the bonding to be slightly lower/recessed is a really good tip. I did not know this initially. Trying to sand that stuff back is a bastard, hard as nails with more inclusions than filler. I imagine that this is what gives it the additional strength for filling the larger holes. Get it close with bonding plaster then finish with filler.
You can also get it reasonably flat with the surface of the wall, leave it to dry for about 30-60 minutes so it is like playdough and you can scrape it back a few mm really easily
