My only good copoly experience has been YoZuri Hybrid. That stuff is all around pretty good and quite strong and I can recommend it in good conscience. I also tried Sufix Advance and had my line break casting multiple times, and P-Line Fluoroclear which handled absolutely terribly to the point it was basically unusable.

Yozuri Hybrid will be what I try if this Maxima doesn’t work out. Then if that doesn’t work I guess I’ll stay with Berkley Trilene or Stren

I tried different knots…uni and palomar.  The Izorline was breaking in the line way up from the knot randomly.  CXX broke once in the line and the others at the knots.  I’m not saying they’re both bad spools.  I’ve talked to a local guide that says he’s had the same issues with both brands too. So idk.  Again I never had this issues with mono 

Well it’s definitely not the guides.  I take care of my gear for one, then two, this happened on 3 different brand new rods.  

Yeah I’ve fished Berkley Trilene Big Game for years now on the same spool.  No issues.  Also have a 25 year old spool of Stren that’s always been stored inside.  No issues with that.  Seems like if I couldn’t/didn’t know how to tie a knot, I’d have issues in the past as well.  

Not suggesting that it’s anything you are doing, so much as trying to isolate a cause. No offense intended at all. I only brought up knots as a possibility based on certain lines’ makeup working better with different knots, and some are more sensitive than others to the number of wraps in a knot (example from my experience: I usually always do 6 wraps in a SDJ knot in 15lb fluoro, but when I switched briefly to a different brand, I found that the knot would burn under the load of an 8XD crankbait. I had to go to 8 in order for it to stay cinched and not move so much).

It’s all good, I’m not offended.  I appreciate the help.  I was simply saying it could be me lol, but I’ve not had any issues like this with mono so I really don’t know.  I have broken mono but it’s always been my fault like not checking the line when I know it’s been through some bad cover with a fish.
 

I know fluoro can be finicky but didn’t think copoly would be like this.  The SDJ knot is one I haven’t tried yet but plan to. I’m going to test the maxima in my pond when it gets here and I’ll try the uni, palomar, and sdj.  Good point on the wraps and I’ve noticed that with thicker or thinner line.  I wanna say with the 8lb CXX I used 5 wraps max as any more made it hard to cinch.  Oddly enough, I’ve never had my braid to copoly connection break.  I’ve use mostly the Alberto knot but also the fg some too.

This year I have ditched the leader entirely and went straight braid. My catch rate has been the same and no worries about knots, line type,  etc.

 

Might be worth considering.

With fluorocarbon, the palomar can skip and is generally not a good knot. The uni with 4-6 is very solid.

As far as the CXX goes, take the spool of it, throw it into the nearest portable toilet, close the door and light it on fire before it can hurt anyone else.
 

 

Few years ago, I tried 8# CXX and I couldn't tie a knot without breaking it.  Never even fished with it.

That’s about my experience with it as well -brittle as glass, and kinked if you looked at it wrong. Come to think of it, I haven’t had all that good of an experience with any PLine product.

Ok will do.  I’ve seen reports of that happening with fluoro.

Yep, that’s been exactly my experience so far

I have found that using copolymer as a leader with braid causes breakage problems because of the sudden shock during hook sets. I have used Suffix Advance as a main line with no similar problems on some big fish. But when I used the same line for a 4 to six foot leader it's was breaking above the hook knot on hard hook sets. When I switched to straight mono of the same test & diameter the problem went away. I assume you are having the same problem. It's not the brand but the type of line that doesn't have the shock resistance when using it with braid.

 What pound test and application. Casting and/orspinning?

Casting using 14, 17 & 20llb. Cranks, topwater & jigs. This is for the straight copolymer main line. Bass up to 11.5 lbs at Lake Baccarac in Mexico. The leaders that broke were 20lb on hard hook sets while shiner fishing in Florida.

Interesting.  The bulk of the breaks I had was fishing in a pond with 1-1.5lbers on medium spinning gear.  No real hard hook sets. I honestly think it was quality issues on the line.  I tried the Maxima Ultragreen out yesterday and had no issues so far after about 8-10 fish.  I’m going to test it further and see.  If I have any other issues, I’ll just go back to mono.  There’s not enough stretch on a mono leader for it to be an issue for me.  I hardly ever power fish.
