I'm spooled up with mostly sufix ice braid and sufix 832 ice braid, as well as sufix ice magic mono lines. I may switch up a little on one of my ultra light combos though. I'm using sufix ice braid with a 1/2 lb diameter and, I believe, 3lb test. I haven't seemed to find a knot that doesn't slip, I may just keep experimenting till I find the right knot though. I'm a big fan of the 832 braid though. It's a little more costly, but I feel it's worth it.
