| Id' say go for a larger pot wherever you have space and 4mm knobs.
I used series 50 with 6mm shaft for monitor level and replaced it 3 times in just a few months. The linear ones are much better, I use several hundreds of dual and triple section, but they still feel cheap compared to series 90. The same applies to Sfernice 12mm conductive plastic, the white ones like in Neve consoles. I have about 450 dual concentrics. If not used for a certain period of time they are harder to move and they crackle. I beleive Neve uses cermet ones, which are said to be better mechanicaly.
Bourns 90 are good, smooth, and after 20 years I can still pull them from my old console and they work. And they are considerably cheaper than series 50.
