So I decided I would take my shakyheads out on my *** and *** black medium. I lost one not sure what it was. Got it to the top splashed then I lost it. Line broke twice on me #12 invisx. Never got another bite. Bad bad day. Many bad words were said

That's fishing... Gotta love it!

Hmmm sounds like user error. (No offense, we are ALL guilty of it). I would bet that the problem is in the knot or drag settings, unless you fish some really rocky bottom. You should be excited about getting bites at all this time of year!

Older line in the sun ?

I remove the reel & store it or put it where no sunshine can reach it..............Not up there either.

Make sure you wet the fluoro before you cinch down a knot. No reason 12# invizx should break of you do that and set proper drag.

My shaky head line is 8# seagar red label, with a polamar knot (again, wet it down before you cinch it). Never have a breaking issue.

Good luck!

I had the drag fine and the line was new plus I wet the Palomar also. I think just a bad day and I backlashed a couple of times so yes it was operator error also haha

This^ and we would know about bites haha

Cayjun red 4# test braid CAN slip over time. I use the    Improved Triline Knot. It does slip on the 4# test,

After tying the knot  I tie a 1/2 hitch in the loose end. then pull hard enough to let the 1/2 hitch JAM against the Triline KNOT.  Never a slip.

Try a San Diego Jam instead of Palomar with flouro.

some people love it but it was probably the invisx, I hate it. Red Label is so much better.

X2.. Palomar has a reputation for being weak w/fluorocarbon.
