I had the same problem when I first started with Power Pro. Now I wet the knot (palymar) befor I snug it up and the failures have
stopped. Doc

For what it's worth, I have had polymer knots come apart on at least three
occasions using P-Pro 15lb and 20lb line. Once with a very large LM, and
twice during casting.
