The best way to see for yourself how great the Seaguar brands are without buying them is to compare them to competitor spools while you're in the store. The process they use to spool the line eliminates overlapping strands and therefore eliminates line crimp. I always used BPS fluoro but noticed how inconsistant line diameter was due to the crimping. I swithed to Seaguar Invisx late last year for this reason and many others. The line is incredibly smooth and is without a doubt much higher in quality and quality assurance than any other brand in my opinion. The Invisx is propbably the most popular right now, but the new Abrasx is supposed to have more abrasion resistance for the same price but is a little stiffer.
