Tim-
I'm with ya on the Royal Wulff....heck, any of the Wulff family works nicely. I also love the Renegade & double Renegade....perhaps because it was my Dad's go to fly while I was growing up. He loved that fly, and threw it religiously on all trout waters. To this day, he will still whip out the Renegade...even when my brother and I are slaying them on nymphs! lol! He always says, "I'm not going to bobber fish"...which is what he calls nymphing with indicators, lol. The double renegade was a staple of ours up on the Snake River, ID during th salmon fly hatch in summer. Caught some monsters on it. Also works on the Green River. Good fly.
