Not a fisherman, but a scale model aircraft builder. I use lead wire of minimal thickness to add detail such as wiring and hydraulic plumbing etc. I was more than happy with the excellent service and help Jo provided by explaining how thickness is gauged. She sent me a sample with my order, which introduced a better understanding to me of what is available for my needs. My order was small but the care and advice were bigtime, major league. You know your stuff Jo, thank you. My order was dispatched rapidly and I received it within a couple of days. Very happy, this is my go - to for any other thin gauge wire needs.
