Its hard to find any in stores around here. I use Triple Fish ordered from Cabelas. For the past few years I've used 100 lb Triple Fish Muskie Leader and tie a Uni Knot. Its nice, neat, not bulky. The best knot I've found so far. I've been experimenting with lighter 20 and 40 lb this year as well, and with it being lighter, other common knots work alright, but I still use the uni.
