I have a new airflo impact running line on my reel. What is the favorite knot for tying a loop in this line? I tied a Kreh in it and the first two failed. The next two seemed fine, but I was not completely at peace with it. BTW, I have one of these on for about four months of practice casting, so that is several seasons of fishing. Today it broke without a knot or any warning, costing me a head. The local boys say "that never happens". Well, not never. The braided running lines do not shoot as well, but if distance is not a big issue, maybe they are a safer bet??
