Try a Palomar knot...you'll have two pieces of line through the hook eye instead of one...More strength
DuffHeres how I crimp300 lb. JinkaiThe first 2 crimps are right and the third wrong--Have to crimp the center of the sleeve--That third one crushes the lineIf you notice the tag end--I melt it down to form a ball to stop any sliding.
I would not use oil or silicon spray or WD40 on your knots...good ol H2O ( Spit ) for me...the water will dry...the oil will stay and perhaps help in pulling out the knot during a long battle with a big fish....
