Wich acrylic for flat brushpainting

I get very nice flat results when airbrushing Tamiya XF, but when brushpainting it often gets shiny.

Is there any tricks to make the Tamiya acrylics brushpaint nice and flat, or should I try something else? What about Mr Hobby?

when i first bought some tamiya acriylics, because i brush paint, i had the some problem. you just have to shake the bottle up nice and well. it probably sprays flat becuse in the airbrush, it gets 'worked' or moved around alot. if you shake the bottle horizontaly, you shoudn't have any probs.
