I have had discussions with old ITT tube lab folks and some NRL gurus of custom vacuum tube manufactury. They advised the 5U$ specifically as one which will deteriorate very little if the fils are taken just prior to use for transfer to air.
I would have to "flash" the filaments and if done well, they should be almost as good as new in a fusor. The key is to avoid the water/oxygen- tungsten cycle common to degrading tungsten and vacuums in tubes.
