I'm running plastic pipe in the ceiling, and dropping down a short
tail in copper prior to re-boarding and plastering. The tail will be
about 6" - so not a huge amount of pipe between the blow torch and
the plastic joint. Is this likely to end in tears? Should I use copper
for the final section in the ceiling as well, so that I get more like
18" of pipe between blow torch and plastic, or am I wasting my time?

Can't you pre-assemble the copper bits and do all the blow-torching
before connecting it to the plastic section?

Or have a compression joint between the plastic and the bit you need to
solder? And, of course, undo it for the soldering process. Maybe 6" and
precise location means this is not possible.
