I was given some last year to field try. We initially started rigging them with live bait hooks and were casting them from a spinning outfit. They were not quite heavy enough to get a good cast but on the overnighters, you really do not need to cast that far.
What we found worked the best was to set them out behind the boat and let it drag while we were drifting and chunking. Worked pretty good on black and a a few yellows.
Yes the smaller size is going to get you a few blackfin hits but that is not a real problem. What is good about them is when the hatch you are trying to match is small flying fish, you have something to throw.
I hit the store at the same time as one of our other captins to give a review of how they were working. We both reported the same thing, we wanted them pre-drilled with a hole down the middle to make a chain out of them for trolling. The store owner called the Yummie rep while we were there and we were told that they were going to add a mold that would allow them to make them with the hole, we will see.
The small ones are not large enough to place styrofoam into. I had an idea to shoot them up with air from a syring but have not tried that one yet.
