I recently ordered a spool of 8lb Yo Zuri Hybrid from a well known online retailer. First thing I noticed was that there was dust on the inside of the package. Was kind of wondering if the line was old?... Oh well I was excited to use it so put it on my chronarch 50 and started fishing.

Well I have been using it for a week now and already have broken off twice on hooksets. I have it matched with a medium power XF rod so it's not like I'm using too heavy of a rod. I used 4lb test almost exclusively the past two years and have NEVER broken off on the hookset. It appears to be breaking at the knot. I don't know if this line has awful knot strength or if it's old, but I can break it off quite easily with my hands. With 6lb CXX I have to at least try when breaking with my hands but this stuff is almost effortless. I am wondering did I just get a bad spool or is this line typically weak at the knot?

Send it back for exchange.

Just like RW said,send it back..iv'e use uni,improved clinch,dropper loop, Palomar knots and never had a break off with this line. i actually dropped down to 10# test on a lot of my set ups and have not broke a rig off except when stuck up on a good timber/stump,and even then i've gotten jigs back w/ straight hooks.!
