I started using Lifecolour lately and I also find them very useable (much better that Xtracrylics ... for my working style)
I used them for brushpainting and airbrushing and had no problems. .. e.g.
for airbrushing. the sand and brown are Lifecolor.
and brushpainting ... base colour airbrushed; green is Xtracrylic and not fully dry yet
all the best
