Presentation is #1. If you present your gear right, you will be successful. But i believe strongly that fish change their bite habits on a day to day basis(barometric pressure) some days a 1/8z pink/white will get hammered, next day you wont touch a thing. Switch to spoons and wham...
Last summer a buddy and I spotted a nice 3 salt summer run laying agianst a boulder in mid-stream. Both of us adjusted leader length to be within inches of the fishes nose. Both of us started off w/ 1/16oz jigs...We threw every color we could possibly think of without a look. Next we tried the ol' shrimp tail, nuthin. Out went a tiny brass teardrop spoon..nuthin... Over an hour had gone by and it was time to move on so i took out a big ugly purple jig and threw it figuring the fish would spook. Fish darted out of his hiding spot the second the jig hit the water and nailed it on the drop....One of the coolest things i have seen.
Steelhead never cease to amaze me...
