I would say you should probably avoid swivels. As far as line, I use 6lb P-Line CX Premium(Fluorocarbon) for jerkbaits. It is really strong, low memory, has thinner diameter than Vanish, and is cheaper (I think). For jigs, 4lb is probably the max you should use. I love green Maxima in 2 lb but there are some other good brands out there. Lots of people use Vanish or Tectan, and I bet the P-line in 2lb would be pretty good as well.
