What I have found with this method is that if you really start trying to adjust the pull left or right in an effort to stress test the pull, the pull bottom wire is twisting at the connection point to the bait and ultimately will loosen to the point it won't hold the adjustment you are trying to make.
So for those folks using this method;
- how deep are you inserting the wires
- what gauge wire are you using
- what size hole are you drilling in the lip per size wire in use
- do you have problems with yours loosening or creating a gap
