    Good budget line
    Chris (Louisiana) | April 15th, 2023
    This line was recommended to me as a budget alternative to some of the higher priced weight forward lines. Have to say it casts great and has worked perfectly for my needs. Streamers and large nymphs in a warmwater setting. It is well worth the investment if you're looking to save a bit of cash.

    Good bass line
    Michael (Peoria, IL) | September 30th, 2021
    I fly fish for bass quite a bit in the Midwest. This line seems to handle the warmer water without a problem and can still tackle with finesse the Driftless Region region trout creeks when called to duty. Especially like using this for smaller streamer duty and the larger hopper/dropper setups.

    I got this line for my fiberglass rod for a different feel and fight on fish. Works great and casts well for the the cost. Recommended for all purpose and use line.

    Great budget line!
    Jason (Texas) | April 2nd, 2021
    Not wanting to break the bank I purchased this for my 4wt setup. It fishes great, it turns over some heavier streamers and dropper rigs with ease, but can still make a clean soft presentation when needed. Great line for the money.

    Great Line
    Chris (Maine) | February 1st, 2021
    I bought this in a 6weight and use for throwing heavy streamers for bass and trout. Line handles well. I like the gray color as well, not too flashy or loud. Recommended.

    Great Line for Nymphs or Dries
    Jake (SW Idaho) | November 28th, 2020
    This 5wt line works great with dry flies or with an indicator and double nymphs. A great line for trout on small to medium rivers.

    Great fly line
    Brandon (Lake Tapps) | October 9th, 2020
    This line has been great on my 5WT. Its a very versatile line, works great for streamers in the lake and putting dry flies in the spot you need it. I highly recommend this line.

    With so many different lines this line is an easy option to choose from, for one of the most versatile ones on sale, this line is unique, having the ability to maximize different casting styles, I would recommend this line to anyone looking to have a decided advantage when throwing against any probability. When a longer cast is needed, this line is exceptional. The line does not stick to the rod guides and instead shoots effortlessly through them. Having such power in a line should be a part of any angler's fly fishing arsenal, the line helps experts reach their full casting potential. This line excels in all types of long distance launches and at a low price, it is fantastic.

    Good line
    Dominic (Lisbon, Ohio) | May 1st, 2020
    I threw this line on a 6wt last year for smallmouth bass and was impressed, so I purchased the 7wt for another rod. It casts well, but time will tell how it holds up. So far so good. Nice line for the money.
