I wonder if adding a thermistor like a CL-90 would completely eliminate the surge ?

I looked at the specs for the CL-90, and you may very well be right.
Have you tried it with a conventional ballast? Shall I?

I used one in my Hallicrafters series strung set. It definitely provided a soft start. It does get a little hot during operation though so mount appropriately.
