I've been advised by the resident airbrush expert (We all know him - Djinn24) to buy a spare needle with my airbrush. I figured I'd buy one/two of these with the set. Now for my dilemma... I don't know if the Badger Renegade Velocity takes a fine needle or an ultra-fine needle. Heck, it might even take both... If this is the case; which would be better for someone just starting airbrushing? If it doesn't take both, which does it take?
