No need for the 3-way for FNF. I use 6 lb green P line and wrap the line 3 times around the bottom clip of the bobber. Works great for me. Landed a 6-4 and 6-6 plus several over 3 on this setup without problems (See posts on KY Board) I know several of the guides use Fireline from the reel to one swivel thn Vanish or Transition from the 2nd ring to the jig and hook the bobber to the 3rd ring. This is all well and good and I am sure it works but too much trouble for me. Too many knots to tie and with wet cold hands all more difficult. More knots more chances to break off I believe.
