I think if we found the truth a lot of the lines will be coming from the same workshops, just like reels blanks you name it. Not too long ago there was three manufacturers of fishing line in the world,yet people used to argue about one being better than the rest. When it comes to fishing I suspect it's a small world. But a busy one. Cortland are made in the USA so I guess we can leave them out of it.Makes you wonder eh ? One thing I didn't mention which I suppose I should in these enlightened times is the environmental impact of manufacture. Do Maxcatch manufacture to the same standards ? Or vise versa. I know nothing about manufacturing fly lines but maybe someone on here does.
