I read were one of the BOC tested some line using digital scales and a slow pull method to see at what point it would break. I was respooling reels last night and decided to do a little science experiment of my own today. I had 30#test Cajun Advantage and 30# test Berkley Big Game Hi test (solar green) on hand. I cut 2- 6 foot pieces off each spool and tied a loop in each end. I hooked on loop onto a nail in the work table and clipped the scale onto the other. Berkley 30# test snapped at 36 pounds of pressure initially. As the other tester did I retied and pulled a second time. Snapped at 24 pounds. Cajun 30# test snapped initially at 31 pounds of pressure. Retied it snapped at 30. The test was repeated with results similar (within a pound or 2 of first test). Just thought I'd share that with you. I just think it is amazing that someone figured out how to take a piece of cheap plastic that is only 23 thousandsths of an inch thick and make it withstand 30 of pressure in tension. Fish on!
