    Posted by Ed on Oct 5th 2022

    I placed my order with a very helpful and courteous young woman who was extremely knowledgeable. My order arrived on the east coast in two days. AvidMax is now in my favorites and on my speed dial. Thank you again.

    Rio mainstream fly line DT

    Spend the extra money and get a better line. I like Rio line but not this. Feels like plastic and too much memory.

    Best prices and quality customer service always

    Posted by Chris Palumbo on Nov 28th 2017

    The Rio line is the best fly line for any type of fish, no stretch, high strength, and perfect action for chucking plugs or just laying down a fly with no effort, and Avid always comes through with the best prices anywhere for line, and all other products you may need, forget the rest and buy from the best, AVID for life. Thanks

    Needed a reliable floating line

    Posted by Jory Reid on Jul 13th 2017

    So far this is a great and reliable fly line. I can easily cast 50-60 feet accurately and so far it floats exactly as it should.

    Pros: casts easily, handles well, accurate and floats well
    Cons: the memory is pretty bad, stripping is tough as it sticks in the hand sometimes, doesn't cast heavier flies very well.

    I like this line and it does what I expect and I would buy it again for other rods.
