Alan, I have not used mono with the Chamberlain release, but the braid has worked without any problems. I use 30# for Salmon, and 10# for Kokanee. They really worked great with the Kokanee, releasing with every fish, what a difference not having to jerk the line out of the clip, same goes for the Salmon. With mono you should only need to twist the loop 4 or 5 times before attaching it to the clip, with the braid I twist it 8 times, try more, or less twists, if you still have a problem, email Chamberlain and he will work it out for you, he is a fisherman, and a nice guy. I replaced the wire on my Scotties with 150# Spectra and like it a lot, no more line hum, less blow back on the ball, no kinking, and no electrical charge going into the water. Ken
