Look up Klein knot on YouTube. It will say Repel/ Behind the line with Gary Klein:Strongest knot. I listed knot as #1 because I figure that is causing your issue. Tungsten #2 because it is very hard on line and you better retie often.

This knot is one of the easiest I’ve ever tied once you get used to it but I only use on fluoro. Tied correctly you will hear a “click,snap,or pop” depending on your hearing. Be sure to moisten before you cinch it because fluoro burns easy.
