Dorber has been selling line for years. Tried some at one point and haven't bought any since.

I doubt that Rio, SA or Cortland will price themselves out of the business. They've been around a long time. Walk into any fly shop, or big box store and whose line do you see. If cheap fly lines were just as good as the higher priced quality fly lines, who do you think fly shops and the bbs would carry?

And remember that all three carry lines at different price points to appeal to the budget of most fly anglers. And no I am not a rep for any of those companies.
