I have had my eye on this line for awhile and was wondering if anyone here has tried it for a finesse line?

Tectan is incredible line...one of the best mono's out there and is never mentioned.  It is the 'Stren' over in Europe, and is the #1 selling line over there.  It has the smallest diameter per break strength I have ever seen.  I tried the premium plus, and it was thin, strong, and abrasion resistant, but it was a little stiff for a spinning reel.  I'd use it versus Pline CXX if it were cheaper,  but it is significantly higher priced.  They make a line called Senso-Flex that would be perfect for spinning reels.
