To me, if you have one dual-action gravity feed to do fine detail work, you might not need another. However, it really depends on the type of things you do. If all you do is fairly small detail work, then you may not need another type of brush, unless it dramatically improves the end result.
i was a professional illustrator for years (long ago!) and my super fine Iwata was what I did all my detail work. but, when I needed large swathes of color I went with a single action, large Paasche - if fact, it had no needle - just used the pressure to blow atomized paint. You had to run it at around 40-45 psi.
Nowadays, I really never use my Iwata anymore, but still use big single action brushes to do large areas, base coats, priming, etc. And the best part is you can pick up a suitable single action to paint larger areas dirt cheap at any discount freight store for around $20
