I'm looking for some recomendations from people running clarke guns/

I'm wanting a general gun to prime/paint/laquer, anybody know which gun is best?

Also does the nozzle size effect finish, 1.2 / 1.4 / 1.8? My compressor is big enough for any but just wondering if there is benifits to the sizes other than hp required.

Sounds daft as I work there BUT havent used a clarke gun but heard good things about them and would like some first hand knowledge from guys that have used them.
