I fished ande mono from 10 to 33 and it never let me down for bass, rockfish, crappies, pickerel,perch,sun fish, ect. Then 2 years ago I got "serious". Now I have a spread of braid, fc, and mono. I could have trusty ol ande on em all, but i like certain things about each line I use now. Those things help me fish more confident. Does it make me better? IMO yes. The more confident you are the better you fish. If you fish a variety of techniques there is a line out that can help you fish it to the best of your ability.
