Float down, GB and Huron salmon sure do inhale roe, not sure if this is instinct, aggression or what, but it works. But like Float down has suggested, try different things. I always try to change things up, if roe doesnt work I may try flies, pink plastics etc. Also when drifting I stall the float periodically to make sure the bait is presented infront of my float. Also shotting patterns differ based on the clarity of the water. Finally, I find that it is alright fishing larger hooks shorter lead when there is a lot of water colour, but as soon as the water is clear, I really size down. My first two steelies this year were out of clear water with size 14 hooks and 3 foot leaders.
