if anyone wants me to make them one, let me know. PM me I've got a lot of. both gammon and allmark reels here. electric tape is a bit crude so thinking of better options. I want a better string, spider wire spectra or something. right now I have used throw line which I see is a bit chunky. more friction. If you go to a three pound spring, you sacrifice either length of pull or bulk of the whole unit. there is also speed, the stronger the spring the faster you can go but again you start having to increase size of whole unit. My preferences have swerved towards as small and light as possible.
