are the knots on your loop on opposite sides? That is one things guys do who tie loops wrong the knots have to be facing in opposite directions, if not the loop may want to twist on the string. If you post a pic of it I can tell
bingo.
DO NOT USE A METAL LOOP!
Those things are junk. Too heavy, they tear up your releases and can really damage your cable gaurd. If you use a release with a metal loop you might as well throw it away if you ever go back to string loops.
I can't count on both hands how many cable gaurds I've seen all dinged up because of people using metal loops.
