you are going to get all kinds of answers with that one. but I use 4 different color maxims on my reels ultra green, hi vis, chameleon, and fibre glo. all in 8 lb test so when a kokanee decides to go wide and takes out the next rod it is a lot easer to untangle with 2 colors. for me it also has a nice dependable stretch which is really important in the early season with there soft mouths and they really don't care what color your line is any way. that is what I use and why. dfly
