I found some female fat caps that fit the rusto male valves really nice and deliver a nice flare and control here ---> http://www.ebay.com/itm/50-FEMALE-R...s-Nozzles-Tips-pack-of-50-caps-/252602484405? The skinnys I was using are no longer available. Wanting to do really clean super skinny lines, and I know I should just get the hell away from rusto for that, but im old school i guess.
