I have been using the barbed paralyzer tip by JBL, but every decent size fish i have speared (mostly perch) flops off the end before i can really do anything. I'm anxious to try my single point double flopper tip so the fish will actually stay on. Does anyone have any experience using these? I know that they are thicker, and with 2 floppers it makes it less smooth, how hard do you have to shoot to get it through an average fish? Any advice would be great.
