I have used a loop for several years without fail. I tied my own. Then the last 3 or 4 years I've had Len putting a new one on when I had work done or strings put on etc. This year(being far from Len) I put my own on. Well I was out of practice. Well I got it a little long. It worked, but it wasn't right. After a couple days I said this is stupid. I cut it off and put on another. GOt the knot a little close and didn't put a big enough melt on the end of the string and it pulled through the 3 shot. So after a fat lip I did it again. LOL The fat lip changed my anchor. LOL I now make sure I flare that bead melt enough. LOL
