I like the topic I have always used the four to six inch Dink floats in black and green. I dont think that these floats will spook an agressive catchable steelhead in even crystal clear conditions. I do like the posts of steelhead coming up to eat the floats!! Thats fun stuff. I think the first fish I rose to a float was on the gold river, it actualy took it down for a yank. I have one float that has teeth marks in it from last march on the hoh were three fish decided it was the better presentation. I fish the skeena area in the fall and primarily fish dry flys I think this is a fascinating way to fish for these critters and very effective.
