Just connect all three browns together, leaving the blues disconnected
for the time being, turn on the power, and probe the three blues in
turn.

There is no need to go playing about with the circuit while energised.
For most cases just turning the circuit off, and then measuring
resistance between L&N on each cable, while operating the switch will
soon find it.

Well, that's true enough, but the trouble with ceiling roses is that
they're
bloody high up. Therefore I suggest that it's easier and safer to probe
one-handed with one of those little screwdrivers with a neon light in
them,

Those screwdrivers with little neons are about as safe a licking your
finger and using that!

Rubbish.

(they routinely give false positives and false negatives, and can never
be relied upon where there is doubt over a circuit being live)

I don't think one has ever lied to me.

while using your other hand either to hold onto the step ladder, or to
steady yourself against the ceiling while precariously balanced on the
top step, than it is to wield one probe in each hand while holding the
meter itself between your teeth.

A set of croc clip ends for your test leads can help greatly,

I dare say. But a neon screwdriver is still more convenient.

If one can test on a dead circuit, then
it is almost always preferable to working on a live one.

Where's your sense of adventure? :-)

You save that for when you climb the ladders with the chandelier.
