The easiest way if you are using coated wire is to put snap or swivel on wire. form loop and twist tag end over standing line. You then pass the twists over a flame (lighter or candle), this will fuse the twist together and result in a very strong connection. Just remember you are trying to fuse the material together, too much heat will cause it to burn off and you will be left with a weak connection. It takes alittle practice but is really easy once you get the hang of it. I have used this method sucessfully for gator blues (15+ lbs) and have never had one fail, and the best thing is there are no additional tools or supplies needed. If going after larger toothy gamefish, I would use single strand wire and a haywire twist.
