If it floats, such as plugs and even corkies, then you can use trebles. If it sinks, such as spinners and spoons, then you must have a single. I have had wardens give me a hard time during salmon season on the Sky for having a treble on a plug but if it says "non bouyant lure restriction" in the regs and there are no special or emergency regs in effect, then it would never hold up in court if you got ticketed. I run single siwash for the most part anyways.
