Thanks for all the info, Currently I'm only using 2 chips (and opto isolators) to multiplex the display whereas going static looks like it will increase the complexity quite a bit. I'll see how bright I can get the tubes without the current getting excessive. I've also found some neat little PIR modules that can be easily incorporated into the design.

They do work fine as direct drive tubes.
