I wonder about this tradeoff:
80 lb Threadlock is about .420 mm (100lb Threadlock is .520, so that is not an option.)
100 lb JB Hollow is about .433 mm

So you get a little less 100lb JB hollow than 80 lb Threadlock, but you can pull harder on the 100lb JB.

Which is the better option?

 

The actual breaking strength of braids aren't what they are listed. JB 100lb might break at the same of 80lb Threadlock. I know you do alot of pulling with your machine's but im unsure about the ABS of both of those lines

 

And I have not figured out how to do a true or any standardized ABS with my machine. I wish I could. The fixtures to hold the line, by Instron or MTS, are way out of my disposable budget. So I can compare line to line, but not provide any valuable ABS figure. Paulus was not kidding when he commented, in effect. don't try this yourself.

My next trip is JB Line One sponsored, and all my reels are full, so I am not going to be doing any comparisons anytime soon.

The oddity of JB 80 being slightly bigger than JB 100 is because JB 80 is 16 strand and the 100 is 12. 80 JB definitely lower breaking than 100, as I have played with both in the context of trying to get my knots better. (I am learning to hate FG.)

 

Sometimes you'll hear a deckhand ask "Ok, who's fishing the yellow spectra?".
If your bait is heading for the corner and you can see it's a clusterf*k, reel in your bait before you get there. That's one party you don't want invited to.

 

Try the triangle method for the FG. I was bad at it untill trying it that way

 

Using Paulus data JB 80 and 100 hollow is a close call on ABS. My personal thinking is that 80 solid comes off the reel much better than both. So your issue with the FG knot is where the line breaks inside the knot in testing? I have not used the FG for 100# and 130# solid yet but plan on doing so. In my mind it is a fair trade off on how it casts and comes off the reel. And I get to use my new hollow to solid splice to have some fresh Spectra on for each trip,

 

Usually once I step above 100 I'm using holow or wind one with a Bimini twist to a looped leader

 

Unless you are Lou Ferrigno, you can pull as hard as you can on both and not break either one.

 

Me too... but I am open to adapt. Just 100 feet of solid on top of what i have might work better. Worth a try at least. I will give you a report on how it works.

 

I am too but once I get around big fish I start to trust my knots less

 

I do all my nail nubs with 65lb now, I can't break it. I was using 30lb and 40lb but I broke it often.
I'm leaning towards filling the HXJ Raptor with 300yds of 60lb JB hollow, which breaks at 90lbs according to Paulus, then splicing in 80lb solid, hopefully for 150-200yds. FG knot to floro leader.
Ducksbuddy showed me how to tie it on my last trip. Took some practice before it stopped unraveling but I can tie it well now. It holds with 45+lbs of drag now.

 

I one time made the mistake of getting 80lb braid stuck on the bottom. As far as I could tell it would make an effective anchor line lol. I’ve never broken 50 or 65 either. Almost always my knot breaks or a hooks straightens out.
