Seaguar Smackdown Braid Review: 20 LB Test At A 6 LB Mono Diameter

Seaguar Smackdown Braid Review: 20 LB Test At A 6 LB Mono Diameter

What’s the answer to achieving a thinner braided fishing line? Some lines, like the Power Pro Maxcuatro, use only 4 strands and a tight weave. Seaguar Smackdown approaches the solution in a different manner. Rather than having a rough 4-strand weave, they stick with an 8 micro strand braid. The result is a smoother braided line, better for casting, and easier on your gear. Get the rundown on Seaguar Smackdown braided line in the following review.

Key Features

8-Strands Of Micro-Dyneema

Most braided lines reduce the number of strands in the weave to get a thinner diameter. Seaguar Smackdown disagrees with this philosophy. In order to keep an 8 strand weave, however, means reducing the size of the strands themselves. With 8 carriers on the braiding machine, each one has a spool of ultra-small micro-Dyneema line. The resulting line has the round profile of an 8 carrier braid with a much thinner diameter.

Ultra-Thin Diameter

The most prominent feature of Seaguar Smackdown braid is its thin diameter. Seaguar provides the specifications to prove it as well. They boast that the 20 LB Smackdown has a diameter relative to that of 6 LB monofilament line. Specs of the Seaguar Smackdown 20 LB test are 0.185 millimeters or 0.017 inches in diameter. Compare that to 20 LB Power Pro Maxcuatro which has a diameter of 0.019 millimeters. They are virtually the same and the Maxcuatro uses only 4 strands.

Round & Smooth Profile For Casting

One of the reasons for using an 8-strand weave is the pattern results in a natural round profile. Weaving with 4 strands may achieve a thinner diameter, but the pattern leaves unavoidably rougher edges. The round profile of Seaguar Smackdown braid lends a smoothness that extends casting distance. It has less friction through the line guides and on the reel spool, meaning it won’t wear so heavily your equipment.

High Abrasion Resistance

Anglers appreciate Seaguar Smackdown for its durability. Smackdown braid uses a solid filament core which adds to its smooth profile. This also increases the property of resistance to abrasion. You’re better off with 8 strands when knicks or cuts occur, but braid will fray over time. Seaguar Smackdown doesn’t dig into itself on the spool, even with lunkers stripping off yards of line. And a braided line that doesn’t dig won’t fray as fast as ones that do.

Excellent Knot & True Breaking Strength

What does true breaking strength mean? It means simply that Seaguar Smackdown braid will break very close to its stated test. Wouldn’t you want a braid that breaks over the test limit, as many brands do? At first glance, that seems to be a desirable quality. But think about it for a minute. By gaining that extra strength, you lose length on the reel spool. Seaguar Smackdown allows knots to cinch and hold with a lot more line on the reel.

Pros & Cons Of Seaguar Smackdown Braided Line


Seaguar Company LogoTwo of the most profound advantages that come using Seaguar Smackdown are its round profile and super thin diameter. For anglers who need good casting distance, Smackdown makes it possible. Like all braided lines, it is sensitive and doesn’t stretch. The 8-strand weave of micro-Dyneema material is incredibly strong and will cut right through kelp and other types of vegetation.

Any angler with experience using braid can understand the frustration of line that digs on the spool. Smackdown offers one of the better lays among braids and resists the tendency to wrap into itself. Anglers get more line on their spools with Seaguar Smackdown and count on using it for quite some time.


Seaguar Smackdown offers some great qualities, but it definitely has its drawbacks. The braid was originally available in Hi-Vis Yellow and Green. Now the Hi-Vis Yellow is out, though the Stealth Gray is a new addition. So there are still only two colors, and anglers have only one choice in spool length. It really would be favorable, even though it’s a Tournament style braid, to offer longer spools.

Not that the construction style would be well-suited to lighter or heavier tests, but the limitations are worth pointing out. You won’t find less than 10 LB or heavier than 65 in Smackdown spools. It’s a braided fishing line for a narrower set of uses than other name brands.

Best Use/Fishing Style For Seaguar Smackdown

For freshwater bass fishing, Seaguar Smackdown has plenty of uses. Its thin diameter can be a big blessing when fish are line shy and it’ll cut through most aquatic foliage. The range of available tests and a 150-yard spool fit right in line with most freshwater bass situations. Smackdown makes a fine choice on your spinning or baitcasting reel. Pair it with your favorite freshwater bass rod, or for saltwater consider the Shimano Teramar.

Moving over to the ocean and saltwater applications, Seaguar Smackdown is more limited in its uses. It will still make a great braid for fishing lagoon bass or targeting inshore halibut. Offshore anglers can make good use of Smackdown on their lighter outfits. 150 yards will fill most baitcasters or 20-30 class conventional reels. Finally, the extra casting distance is perfect for kelp bed fishing along the coastline.

    So far so good. Traditionally I have been a power pro super 8 user. Saw this and was curious. Spooled up 20# on a stella 2500 mounted on a loomis GLX drop shot rod and put it to the test at Lake St Clair.
    Smooth casting , great visibility with flash green, and strength to spare,
    Didn’t notice any wind knots and abrasion wasn’t an issue because I use Tatsu fluoro leader.
    Holds an FG knot very well
    Liked it enough that I bought another spool
