Trevor makes a good point about matching the line to the rod. IMO no one line is right for every rod. So often I hear people say they like brand X or brand Y. I don't think enough attention is paid to matching the line to the rod. You wouldn't put the same tires on a Ferrari that you would your 4x4 pick-em-up
There can be quite a bit of difference in lines of the same line weight. Not just taper and running line diameter, but actual weight.
As you can see there can be quite a bit of difference in lines. I'm sure Walt has chosen the line he feels will preform the best for a reason
