For what it is worth…
I have been much more successful downrigging for Lakers with single hooks rather than trebel hooks on my spoons.
I have changed almost all trebel spoons out to Gamagatsu Siwash hooks.
I have found the longer shank gets a deeper mouth hook set than trebs that tend to lip hook more for me, resulting in lost fish.
I like to bend the gap out a bit (sideways, so if you lay it on a table the point would be bent up some) and sharpen them up. I feel the offset gap tends to hook better and might snot slide out of the mouth quite as easy.
Who really knows, it has been working better for me so I will keep believing it. Good luck on your trip, maybe this info will help on pike???? -Mark
