Corbo, IMO it's not the inability to tie flouro to mono that's causing you issues. It's the mirage, unless something dramatic has changed that stuff was awful. Try the Umpqua Super Flouro or the Frog Hair Flouro. Both are much better in my opinion. Also, tying a yarn indicator into flouro will cause a major weak spot, it seems flouro cuts into itself and the knot used for yarn won't generally hold in flouro.
