"has anyone tried shooting with an Aaton at 24fps under fluorescent lights? Did a test recently on a Bolex, loadsa flicker at 64fps (no surprises 
there) but not at 8fps (from what I can make out from a very short bit 
of roll-in) I shot some Dan Flavin's a couple of years back on a K3 at 24fps which looked fine"

is your Bolex crystal sync?  my guess is that at 8fps the shutter was open too long for the flicker to really affect it, where as at 64fps you were getting all the flicker detail.   Also, all fluorescent bulbs (tubes?) are not equal- there are 'flicker free' versions which are quiet expensive, and cheaper ones that flicker badly, so if you do tests be sure to use the same lights and camera that you will be using for the final project.

I think the general rule is is that if your camera has crystal sync than you pretty much have to use flicker free tubes- but if you are shooting non-crystal sync than you may actually have a bit more leeway.  I know Jem Cohen often shoots fluorescent lights with a non-sync Bolex with beautiful results- it's as if the flicker from the non-sync camera equalizes the flicker from the bulbs.
