Hey Bodie, if the locking move is breaking strings, don't do it. I've changed strings many times and didn't push on the wing. If they are setting the string against the cam then they work just fine. The reason to do it is to "lock" it sure, but if it is already locked you will just be pressing down and flattening the string. That flat spot is what is breaking. If you have to pull down on the wing to get it to release from the string when you are taking strings off then it is already locking.
