I started using it last winter. Learned many lessons quickly. Most of the knots I tried would unravel if a big pike hits really hard. Didn't really like the way it tied any way. So then I started using crimp sleeves. I make quick strike rigs so i use a barrel swivel crimp sleave. Then I started running leader through another crimp sleeve around the hook and back up through the sleeve. Again if an big pike hits it hard enough the leader will come back through the sleeve and you will loose a fish. So now I wrap the leader back around through the sleeve a third time. Its been working pretty well now. Though I have broken a couple.
