OOOERR - knots in synthetic line. isn't there some sort of techno law against that?
If it works its works, right !
(Also a reason to use the double figure 8 knot as that knots has the line make bends with a larger inner radius and thus reduces its break strengh less. There is a whole science associated to knots and there are a few very attractive knots that leave most of the line strength unaltered.)
