Looks like most on here agree on hi-vis....but, I know of a couple of my fishing buddies--one uses clear line and one uses hi-vis--that were fishing a clear water lake and my buddy that was using the hi-vis couldn't get a bite to save his life while my other buddy was catching fish right and left with the clear line.....and yes, they were using the same baits.....next time they went back, both had on clear line and both caught fish....
I am sure you can catch fish in clear water on hi-vis line as most all of you can attest, but I believe it does have some kind of affect on clear water fish. I don't believe you will catch AS MANY on hi-vis as clear line. JMO and you know what they say about opinions. Would love for some other people to chime in on this with their stories......
