Bought the 130lb to make leaders for musky fishing. It wasn't as thick as previous bought pre made leaders but I read it's new and held up just as well. It saved me money making them compared to buying pre-made.

Resite tallones fuertes. Es un buen material para pesca.

This review has absolutely nothing to do with fishing - it is for using these as instrument strings - specifically Charango and Ronroco. It is a common thing to on other instruments - just look it up on Classical Guitar or Ukulele forums.For Charango strings I have I tried Dogal D114 - nice nylon sound with perfect intonation but a bit too tense for my long scale of 39.4 cm, La Bella C80 - way too high tension, bad intonation, Medina Artigas 1230 - good intonation but a bit tense and a plucky attack with too dull decay (some really love this set though), RECENT Aquila 1CH - slightly plastic attack, not as good sustain and too tense compared to old 1CH, RECENT Aquila 2CH - still not good sustain but better feel on the long scale, slightly plastic attack, and finally Savarez Alliance KF which had a metallic attack, dark sustain, not musical feel or sound, and are very expensive as single strings.The Seaguar Premier are the BEST. The intonation is perfect. And trust me I am PICKY about intonation because the charango, like a mandolin, demands it. The sustain and volume is definitely better. The attack sounds VERY similar to the old Aquila Nylgut but is a little less plucky. It has a MUCH better quality to the attack, sustain, and feel compared to Savarez Alliance. I was particularly surprised by that since Savarez Alliance is also fluorocarbon. The Seaguar Premier feels much softer to play, with much less metallic "ping" in the attack, and is much better for vibrato compared to the Savarez Alliance.The only thing I don't absolutely love about the Seaguar is that vibrato is slightly more difficult than with the old 1CH. Also one of the strings popped off over night because I reversed it so it may be a bit more fragile. They are made for fishing after all! haha. After I replaced that string they seem to be holding up fine.For the price, intonation, sustain, feel, and tone of it I wouldn't use anything else at this point. It is easy enough to play bar chords even on my 39.4 cm scale instrument (tuned to standard tuning).Here are the gauges used of Seaguar Premier leader:Charango 39.4 cm scale, medium tension:E 20 LB .37 mmA 30 LB .47 mmE 50 /20 LB .62 mm / .37 mmC 25 .40 mmG 40 .57 mmI have since tried these same 20 lb + strings on an Argentinian 37.5 cm charango and I prefer the lightness and tone more than anything else.For a regular scale length of 37 cm and fairly strong tension use 25+ lb. This also works very well but I prefer 20 lb +!E 25 IbA 40 IbE *60* 25 IbC 30 16G 50 IbThese Seaguar Premier's just SING. They should really consider rebranding some of these in perfect gauges for every instrument imaginable. Or improve it slightly for instruments. But in reality I have NEVER used as good a string so really they don't need to change anything.

Really good

Excellent product. I caught a 43.5 in 22.5 lb pike using this as an 80 lb leader. I caught 100 pike on this same leader before I caught this one. Just check it for nicks after every catch and replace if it gets nicked. I never had a nick in the line, and you still need to use your drag and keep the line tight. I also never broke a leader. Good luck and I hope you catch "The Monster"!!
