    Scientific Anglers Mastery Grand Slam Fly Line
    Simon (Cape Town, South Africa) | February 2nd, 2021
    This line is a great all-round line for any flats fishing trip. I have it paired with a Scott Tidal 9WT and it's an awesome combination. I have no problem launching big clousers with it, and as I bought it some time ago can vouch for its durability. A great all-round line for all your flats species,

    Nice Line

    Bought 8WT flyline to go with my new rod. This line is nice and smooth and shoots out quite nicely. I am a big fan of Scientific Angler Flyline!

    great line but not durable
    Jonathan (Jersey City, NJ) | August 2nd, 2020
    got this line for fishing for bass in warmer water and fishing the summer months of the year for bluefish when the water temp rises. It is a great line and is very slick and shoots, I wish I could say the same about its durability as the welded loop recently snapped off while I was hooked into a large bluefish. That should not happen, 4 stars because it is a spectacular line that can do basically anything, but just not durable.

    This is a great fly line. Really gets the fly out there in the wind and is very easy to cast. Have a 10wt rod and thought about getting an 11wt line to assist in the casting but the 10wt line works great. Highly recommend this product.

    Like this heavier line
    Andrew (CA) | May 21st, 2019
    This line performed admirably in the flats for Reds and threw well out in the nearshore for Jacks and Spanish mackerel. This line definitely is a full line weight over, I recommend throwing this line a few times before you are out on the water, especially with large flies.

    I bought this line for an 8 and 10wt for a trip to Belize. this is a great fly line. I had no issues turning over heavier crab patterns and clouser style flies on several windy days. With some minor adjustments you could lay this flyline down without spooking fish when out of the wind. I would recommend this product to anyone looking for a general purpose flyline to cover it all if traveling light or on a budget. Hope this helps!
