How much? I have to admit that I tend to think in bigger terms than woodworking, owing to the type of painting I do, so that's my shortcoming in a discussion like this. I suppose for typical small scale painting it could be ok.
How much small diameter hose do you have in your delivery system? Do you so small scale spraying? Are you getting good atomization and patterning? I guess if you're getting good results, that's all that really matters for your application.
