It is entirely possible that I may never use any colored line again for anything but night fishing ever again. Last sunday I was out using a different rod than I normally use (my wife was using my best rig). I was using a rig with the berkley ice blue colored line and had my aqua-vu set up so we could watch both lines. She had steady action with the IDENTICAL set up except for line color. The fish would come up to mine and look mine over and back up, look up & down the line, slowly back away and then move (only three feet over) to her's and SLAM IT !!!
Same brand line, same lb. test, same tear drop, same bait, same motion, SAME EVERYTHING BUT REEL, but that rig had a clear line.
Use what you want, but for me seeing is believing!
