Great string (which my wife uses) but not the same string I was referring to. Tour Super (in any version) is multifilament. Tournament 80 Spin was a solid core syn gut with spin oriented wrap. Totally different animal than any gauge of Gosen OG. Much more spin than any SG I have used over the years. Interestingly, I can still buy in Japan and it is still sold in the UK. Last time I bought here it was <$5.00 set.
