Here is my experience with "size matters". While in Canada catching blacks, we had to improvise on the fly. Fish were biting extremely light. Feeling any resistance they would drop it. While searching for a lighter float in the tackle box we came across some ear plugs. You know the kind you roll around in your fingers to make it smaller? That did the trick. Just large enough to see but easy to pull under. We started hooking fish after that. That day size mattered without a doubt.
