Were you trolling very slowly, and did you have the line tightened down so that there was a deep bend in the rods? If trolling slow and the reels aren't cranked down, when the pin pops that can create too much slack in the line leading to lost fish. If your clips aren't tight enough and there is too much slack in the line it will result in a poor hook set. You could try doing a power hook set when you see the pin pop. Speed up until the slack is out of the line, and you can see the fish is taking out line. Then slow back down and play the fish as usual. Worth a try, to see if it improves our catch ratio.
I mostly use single siwash hooks with hoochies. I bend the hook so the gap is smaller, then I bend it at an offset angle from the shank. This tends to hold fish far better with barbless hooks. I also rig with gammies sometimes as they are great hooks, but I use them far less than siwash hooks.
