I have never cracked a single 0.15mm nozzle either, and I only use createx paints to which I only have slight problems due to the pigmentation saturation of the different colours, which I easily rectify by careful use of thinners. On another note H&S seem to be the only airbrush manufacturer bar one, that has gone forward with the development of airbrushes with the consumer in mind and not just pushing out the same antiquated designs. I'm talking about nozzles and trigger movement. How many airbrushes can boast that not only have you got total control of the paint supply to the tip but also total control of the air being delivered to the tip as well. I use this feature all the time and what a difference it can make. Also my Evolution has perfect control from the moment I touch the trigger on a .2mm needle setup but I must admit their is a slight delay in the .15mm on my Infinity. I very rarely use the .15mm setup and when setup with the .2mm I have never had a problem with trigger control. I have recently purchased a Bartsharpe UK brush which uses the same nozzle setup as the H&S but with the Iwata style of trigger. They have been designed by airbrush users for airbrush users. They also retail at a fraction of the cost (£37) of an Iwata or an H&S for that matter. The brush that I have is equal to my H&S brushes apart from not having the trigger air control. Sorry for the rant guys, just throwing in my two pennies worth. Iv'e got nothing against the Iwata style of brushes, but in my opinion the Iwata is like an old Roll Royce silver shadow compared to an new Audi R8. Both extremely desirable but technologically years apart.
