Personally, I think the hardest bite to detect is when the fish picks up the jig and moves towards me. Side to side or moving away is easy to feel and see but when she puts slack in the line is the hardest. I have been using Flourocarbon on EVERYTHING except topwater and know I have caught more fish because of it but I am giving up the ability to "see" the line under the blacklight at night. I guess it will have to wait until next year to see if I can find a Flourescent Flourocarbon that I trust to use at night. Until then, I will use Flourocarbon to help me in any way possible. The only time I INTENTIONALLY don't watch my line is when I am throwing topwater. I will look around and take in the sights because I just don't have the will power or whatever it is to not jerk until I feel the strike. At least there is that split second after I hear the bust that I put my attention to the general area that my bait should be in to see if it was my bait that got smoked. By this time, I either feel the fish or enough time has passed that it is ok to set the hook. Too many times have I had fish follow my topwater at Dale Hollow in the morning and with the crystal clear water, way too hard to not set the hook too soon.
