Spent a couple hours at Thunderbird yesterday. I was fishing a tube fly tied on a 2 inch plastic tube. It seemed to plane upwards in the water. I was worried that it wasn't fishing at the right depth even with a sink tip and a short leader. The plastic tube fly wouldn't touch bottom at all. Switched to a waddington shank and then to a brass tube and ticked bottom occasionally. Am curious what types and sizes or tubes people prefer for steelheading.
