I have muxed 4 tubes with an on-time of 350uS each tube, but only because i was trying to make some fancy effects, under normal circumstances 1mS over 6 tubes = 6mS per scan = approx 166Hz (fast enough not to flicker) The problem which might be an issue for you is if the brightness seems too low. A lot of people who start building 1 x 6 muxes try also using 2 x 3 muxes (if you have enough uC I/O to spare) and then you find the brightness to be notably better than a 1x6 scheme.
