Spawn-sacks work great for steelhead, but when steelhead turn-off them, pull out the TriggerX 4″ Probe worm and start catching again. I fish mine “wacky-worm” style hooking the worm right in the middle. I use a #12 Gamakatsu hook which I find minimizes getting caught on the bottom and really “sticks” once you set the hook.
When I’m drifting I gently shake my Rapala float rod making the worm gently move up and down below the float. When a steelhead grabs it, it usually shoots the float under!
