I have used Prestige Plus lines for several years in different weights and tapers. Not on bamboo because I don't use it. The lines are the same or better quality of much more expensive lines. Last I knew from a very reliable source, a Cabela's product manager, the lines were SA lines in a Cabela's box. I don't know if that is still true, but I will not hesitate to buy another one when I need a new line.
