Had an idea today but wanted to pick some brains first. Sometimes when making up sword rigs, I find that cripming the hook obviously creates a small loop therefore making the hook "swing". In my opinion, it makes the squid look kinda unnatural since it sorta "bends". I thought that a piece of shrink tubing placed over the leader, crimp, and upper part of the hook would help to keep the whole thing a bit more rigid. Question is, do you guys think that the heat from shrinking the tubing would compromise the integrity of the leader?
