Can't take credit for this one but I learned a great trick from Adrien. If you are using otter boats drill a hole on the outside wing of the otter boat, attach an 18" lead to an empty tin can (I used my wifes tupperware hahaha) and tie it through the hole on the otter boat. When your otter boat is out there it will help put more drag on the line and pull it tighter enabling the release to slide better.
Works well for me. Adrien educated alot of us on this site just how to catch fish and how to release them properly. He was the first person that I can remember telling us to get rid of our "slob nets" (as he used to call them) and buy a rubber net. He has not posted for quite a while, I for one miss his posts and great pics.
