i use p-line fluorocarbon but i don't use a black light i go by fill. i just started doing this all last year and i seem to have landed more and better fish then when useing a black light. if you think about it all the boats who night fish use some type of light. weather it be black, red, green, or white it gives some type of light pinatration in the water. pluse i think that if you use some type of line that you can see under the lights that it glows all the way down into the water to. and like people say that fish will become adapted to the lights and after being cought so many times when a light is around they will be more relucktent to bite. now if you can sneak up on a spot with no light and no visible line and a more realistic looking bait they will be more likely to bite.

i don't know if all of that is true but it sounds good. all i know is that i have cought more and better fish then when i used to use a black light. and this is what i came up with in my head why it works better so if that is what i think and it works then like they all say it is what you have confidence in. just my 2 cents

thanks
