Divers-
The Sage lines are indeed mfg. by SA however they are not complete with SA's trick AST coating.

I absolutely love the taper of the Performance Taper but have always been disapointed with the durability of the coating and prolonged shootability of the line. However, if you take good care of the line, clean it and treat it with Glide frequently, you should extend the life of your line.
