P Line CXX Review: Extra Strong Copolymer Fishing Line

P Line CXX Review: Extra Strong Copolymer Fishing Line

It’s nearly impossible to describe copolymer lines in a couple of sentences, and with very good reason. When you bond or coat two lines together, you get a huge difference in performance depending upon the material. Rising from the clamor of variety in copolymer fishing lines comes P Line CXX. You can toss CXX into heavy cover or pull fish out of rocky holes and still have more pulling power than most monofilament lines. Soak in the full details of this unyielding line in the following review.

Introduction To P Line CXX

P Line CXX LogoSince its inception in the USA in 1982, P Line continues its streak of excellence in the creation of copolymer fishing lines. As an advancement from their PF Original line and the CX Premium, P Line CXX offers the ultimate strength.

Earlier blends of P Line filament lines may offer a lower memory, but none can withstand the shock of angry gamefish like CXX. Add to that a higher level of abrasion resistance and strength vs diameter and what do you get? A line that will straighten your hook before it comes close to breaking.

Note: Due to the enormous strength of CXX copolymer line, many anglers find they are able to drop down a test size. The line has a breaking strength much higher than what it lists.

Key Features Of P Line CXX

Low Stretch For Ultra Sensitivity

In comparison to other mono and copolymer lines, P Line CXX has low elasticity. Like all filament lines, it stretches more than braided fishing line. Still, you’ll experience a much higher level of sensitivity on your rod tip using CXX. That, of course, translates to feeling the small strikes that other lines might absorb.

Extra High Strength Per Diameter

Xtra Strong P Line Reading through different anglers comments, a couple of them complain that CXX is too thick. What these fishermen are failing to grasp is the strength of this copolymer. If the line is too thick, you’ve got way more line strength than your gear is likely able to even handle. Drop down a size or two and you’ll be fine. Though P Line doesn’t provide the true breaking strength of CXX tests, personal experience says 15-pound fishes like 20 or 25.

Incredible Abrasion Resistance

Running CXX with a lure over foundation or rock piles shows the real value of the line. When bass or rockfish strike, anglers know their intentions. They love to pop out of their holes to feed, then quickly withdraw back to safety. When this happens using CXX, anglers are less likely to break off due to its astounding abrasion resistance. You should still keep an eye out for scuffs in the line, but those scuffs won’t cause CXX to break as it will with other filaments.

5 Colors For Specific Water Conditions

Not only does P Line make its CXX copolymer in five different colors, but they also provide recommendations on best use. See what P Line has to say about each color in the descriptions below:

  • Crystal Clear – Clear filament line is the standard choice for most anglers and it fishes well in almost every type of water.
  • Hi-Vis – Strike detection and line management are the top reasons for choosing Hi-Vis CXX. It works well as an indicator when drift fishing, flipping or using black lights while night fishing.
  • Moss Green – P Line recommends Moss Green for salmon and steelhead anglers. They claim it also hides well in freshwater lakes for the tournament or recreational bass fishermen alike.
  • Smoke Blue – As green inshore coastal waters change to a deeper shade of blue, offshore anglers prefer the concealment of Smoke Blue.
  • Fluorescent Green – Another bright colored line, Fluorescent Green helps with both line management and strike indication in open water.

Pros & Cons

Advantages Of P Line CXX 

When you consider its strength vs diameter, CXX may very well be the strongest copolymer on the market. That characteristic coupled with its extremely high resistance to abrasion makes it nearly impossible to break off using CXX. Fishing 15-pound test at the local saltwater lagoons, I’ve straightened out lead heads that got caught on the rocks.

Drawbacks Of Using CXX

By placing attention to strength and abrasion resistance, CXX does suffer in other areas. The largest detriment on the water is most likely the memory of the line. Most of the issues anglers report are while using spinning equipment. CXX will tend to keep its shape over time and the curls will lead to wind knots on spinning gear. Curls in the line due to higher memory will also shorten your casting distance.

Another complaint about CXX is that it is stiff which makes knot tying more difficult. It kinks easily if you pinch it, though the Palomar knot seems to perform best. Angler’s comments express difficulty tying cinch knots with CXX, though I personally never had a problem. At least not with the 15 through 30-pound tests.

Best Fishing Style / Application

P Line CXX Will Pull Heavy Gamefish On Large Conventional Reels

P Line CXX performs well within a number of different scenarios. You can use it to put the drag down when tuna hang, then put the brunt of your rod to work. Whether you’re drop-shotting, bouncing a Cribbs Jig, or presenting live bait to rockfish, CXX can handle the abrasion of their jagged-edged homes. Put it on your heavy iron for the yo-yo technique and it’ll easily handle the shock of fast striking yellowtail.

Lighter line applications include pitching or flipping into cover due to the strength of the line. Even in inshore coastal kelp beds, CXX tends to pull through with your fish intact when other lines break. Drift fishermen and river waders also appreciate the strength of a line that won’t break if it rubs on a tree branch or two.

It’s available on their Contact Us page which, unfortunately, lacks any other means of communication. You can also stop by the P Line About Us page to learn a bit more about the company.

In Conclusion

93 out of 100 anglers approve of P Line CXX fishing line

P Line CXX scores above the ninetieth percentile despite complaints about its memory and stiffness. Anglers who use fluorocarbon are accustomed to knot tying with a stiffer line and the curling isn’t a terrible issue. The strength and abrasion resistance of CXX is uncontestable when placed up against other monofilament lines.

  1. David Compomizzo

    P Line CXX is awesome. I use it on Oregon salmon and rock fishing with no issues. My 30lb test breaks like 50 lb test. Great product at good prices. Can’t wait to get back to the boat show in Sacramento to pickup more.

  2. Rusty Rosenthal

    I use 8lb CXX and can only say wow. I have 4 big bass plaques and over 20 wins with this line as well as 2 unclaimed Muskie state records. That’s right, 2 Muskie over 56 inches both hooked with less than 5 ft. of line out when they bit on 8lb line. At first it drove my partner crazy until I got him on 10. He never fished with less that 17lb line. Now he is even thinking about 8. Can’t say enough about how good this line is. Memory issues are gone from this thin line and water seems to relax this line as well.

    1. That’s a fine testimonial on the strength of PLine CXX. I swear it brings items up off the bottom that otherwise may have never seen dry air again. Lol. Thanks for your time and the comment. Geoff.
