Sufix are (certainly were and i'm not sure if they've changed hands as it's a long. long time since i've spoken with Jeff Rothstein) a US brand. The lines are/were actually made in Chang Hua, Taiwan and also southern China (Shenzhen). I started buying from them way back in 1997 and visited them several times (I don't miss the journey to their factory in Taiwan as it was a bit of a slog). The Wang family are/were really nice people. The problem was Rapala. Once the Taiwanese were all part of that group they dropped their OEM customers like a hot potato so I had to do my research & travel and find a suitable alternative who, nicely, turned out better, easier to deal with, reliable, consistent etc. Then after a short time Rapala (Italy as it happened, everything had to go through there) came back knocking (obviously dropping their OEM customers didn't work out as planned) but that horse had bolted. Far too late. They did have some very good lines (original ESP Carp Mono was one as was the original Super Specialist) as well as braids & coated braids but things move on, other line producers (actual producers not respoolers) advance and things are now very different.
