The new Yo-zuri hybrid ULTRA SOFT is a fantastic all purpose fishing line if you are not a fan of using straight fluorocarbon, braid or Mono as their are benefits and draw backs of every type of line. Not all co-polymers (Nylon-Mono coated or fused with Fluorocarbon, are created = and the diamaters and breaking strenghts vary between brands...
I have been using the yo-zuri Ultra Soft FLuro/Mono blend in 20lb and 12lb on a couple casting setups, and 6-10 on spinning and it handles like mono for casting and stretch, however you do get the benefit of extra strength as the line will not lose 10% of its strength after an hour in the water like mono, and UV light will not weaken the line like it does wiht mono, so I do not have to change spools as often. I also find it to be very good for abrasion resistance compared to lines like Trilene xt,Stren High Impact & with the price point compared to 100% fluorocarbon I am starting to make the switch to all Yo-zuri instead of Fluoro casting lines & straight mono...
CO-polymers are also thinner in many cases, although many companies advertise diameters that are thinner than they actually are, and a great example is Triple Fish which is one of 3 OEM's who make true Fluorocarbon with the other two being based out of Japan. Triple Fish is Made in Germany, and is the OEM for many brands in our stores and catalogs, and in many countries. I tried using the triple fish Rx Copoymer which advertised their 20lb with a diameter of most 14-15lb monofiliments, and the 15lb closer to 10-12lb....However, I noticed that in several studies it turns out Triple Fish and all the companies they make line for are not as thin as advertised, and 20lb breaks at 18-19lb test...
Long story short, I think the only advantage to 100% fluorocarbon lines like Stren Fluorocast, Invisx, and all major brands is the fact that fluorocarbon sinks like a rock, where mono and copolymers and braids float for the most part as some new braids are adding strands of different fibers like gore, Titatium, Fluorocarbon,Mono, Teflon, and other materials to help with the abrasion issues that Braid is known for....
I am always amazed at how many people will buy a certain line like Berkley Fireline or Tuff Line Duracast and some of the spider wire lines and not realize they are buying a coated superline and not a braid. Lines Like Berkley Fireline are great for spinning gear as they are a PE coated line that has a completely different feel from a braided line like power pro which is a 4 strand spectra, and they cast and handle completely different. I have friends who use crystal and PE coated lines on casting reels, but there is a learning curve whenever you change braids...Swithing from Power pro to another 4 strand weave of spectra or Dyneema will handle the same, but if you decide to try power pro plus or Dawia Samurai to name just a couple, an 8 strand spectra weave is a new animal compared to power pro and all the other popular braids on the market that sell in the $15 range for 150 yards. Once you try an 8 strand you will notice the difference is drastic, and they cast like a dream. Quiet, Strong, Thin-Samurai does a 15lb 2.5 diameter that is absolutely fantastic and it is super soft, and allows you to gain casting distance compared to power pro and tight 4 strand braids. Suffix 832 is another great line which is a blend of 8 fibers with a fiber of gore added, and the trend is to now add a strand of Fluoro to make line sink, titatium, Mono, Teflon and other materials to help with memory, abrasion isues etc.
My point is this.......
If you want to get your best bang for the buck, do some research and see what other companies offer a 4 strand spectra or dyneema since they are essentially the same fiber only Honeywell owns the patent on Spectra, and a Japanese company owns patent on Dyneema sk-65 and 71 which is what all modern braids are made with. When Power pro says "Multifiament" it simply means that more than one fiber is being woven together and it is a 4 strand which is has some drawbacks and benefits compared to the much smoother 8 strands like plus. If you like to flip into heavy cover, a tightly wound 4 strand is very good since it acts like a razor blade with weeds, where 8 strands are super soft and roll off your spool much easier without digging in and causing as many issues with abrasion problems...Just think about it....8 strands is more abrasion resistant if woven correctly since you can land a fish if 4 strands get nicked, where you would break that fish off on a 4 strand.....
I used to only use power pro on all set ups, but now look for sales from other quality line companies to get the most for my money as companies like Tuff Line, Berkley, Stren, Suffix, hi Seas, Torray, Spider Wire, Seaguar, rapala, P-line make some fantastic braided lines that handle exactly the same as the type of line you are using.....
Maybe it's me, but I have noticed that ever since I stopped using Fluorocarbon I have not had a knot break in the cold, or from not tying the perfect knot with care when in a rush instead option for either a Mono Leader, co-polymer, and no leader at all if I can get away with the thin diameter since Bass will often be line shy in clear water.
I encourage everyone to try this tip to catch more fish and make any line "invisible" since FLuro is not 100% invisible as many like to believe. Spend $3.99 for a 12 pack of sharpies, and cut a slit down middle of each marker with a razor, and color the last 10 feet of your line or more with whatever color appears least visable in the water you are fishing that day. Red line is advertised as invisible and so is pink, but what is "Clear water" anyway? My pool, spring fed lakes and ponds, Phosphate pits, and brackish and saltwater are almost always clear in winter and the tint of the water make green usually the easiest or fish to see...WHen in doubt throw Green Pumpkin, so why does everyone think Green is Invisible? It is amazing to see how purple, green, and brown smears often make any line truly tough to see above and below the water...
sorry for the ramble, I speak to hundreds of people every weekend about line and am surprised about all the misconceptions about braids and lines, and I am sure I have made statements that are not 100% accurate as every magazine and company keeps throwing b.s. at us to buy their products. I have a company here in Tampa selling braid as being the thinnest and strongest, yet it is coming from an Oem in China who is the same OEM who makes the fake power pro that has poisned ebay with fake Fireline, SPiderwire, and power pro.....OF all the china braids on Ebay and elsewhere, only a few are actually good quality, and if they say spectra or Dyneema they are probably dacron or a coated fiber, 3 strand of similar fibers which are good for a month or two, but will eventually start to unravel, or fail at some point....You can find tests on any braid online, and If braid says 10lb, it should break at a minimum of 12-14lb, and would hope that it could handle 15. If says 40, I would hope it could test out consistently at 55-60 which few lines do, as they vary from pack to pack like a crankbait.
