Guys it's not that the line is breaking at the knots, I can easily break like sewing thread with my hands when the line is straight out of the box. We have used 4 lb line for years and have never had this issue before. We are talking about straight out the box without putting it on reels, it snaps. After sending the first shipment back to BPS, I got a second shipment and 1 out of the 3 spools was good (meaning I could not easily snap with my hand before putting on the reels).
