Just a update on these disks. I bought the size one,wish I would of bought some of the #2 also. I'm disappointed in these disks As they didn't really change the action of either the squids,or the spoons that I was using. I usually troll between 1.5-1.7mph and didn't notice any real change in the action. I tried running at a faster speed over 2.0mph before I noticed any real change. I will give them another try this fall when fishing for big rainbows and browns,when I usually troll faster.
