John, re-read his third sentence. I think it says it all. Seaguar Premier breaks a little below what it's labeled as. Ie 20 Premier will break at close to 20. Most lines labeled 20 will break closer to 30. Sooooo if you pull on Premier the same way you would pull on 30 lb line labeled as 20 the result is predictable......never mind abrasion decrease on tunas little teeth even if you finesse..... I love hearing how xyz line is " the strongest 30lb" or whatever line. No dummy 30lb is 30 lb. Line manufacturers just put 30 lb stickers on 50 lb line and people buy into it.
