Waterbased paints can at times have high surface tension properties, wanting to stick to every surface they get near. Most acrylic lines of paints also offer a flow improver, or a release agent which gets added to water then used to help reduce the paint in the brush. They work by reducing the paints natural surface tension, allowing them to flow easier through the small spaces of the airbrush without wanting to grab on every surface nthe way out.
I would try working with the trident more, before switching brands - as you may wind up starting all over again only to find you are experiencing the same difficulties. Createx (especially the illustration colors) are great for airbrush, but they too have their own set of challenges to learn and overcome.
With the trident, I would try adding a few more drops of reducer, or water to the color cup, and test. Add a few more drops and test, repeat until you achieve a mix that seems to work at the air pressure you want... I generally keep my compressor set to 35 - 40 psi, but do use a MAC valve on my hose when doing detailed work. Crazy as it sounds, sometimes it is easier to get fine details by keeping the paint thick, but using higher air pressure to draw it out of the brush. Practice, practice, practice along with test, test, test, to find what works best for what you are working with.
