Scientific anglers UST shootinghead.
These ultimate scandi taper comes in 10 different types, from float to s1/s3/s5. The new about UST is that you can get them in three-density lines, and that is new from the scientific Atlantic salmon lines.
In this review I had test the floating/ hover/ s3, it is similar qualities as f/int./s2 but gets the fly down deep. It is easy to cast with, and goes perfect when you drop off your throw out over the river. A great choice for when fish are lying in deeper water, and where fly speed is the key.
Another bonus is that this lines doesn’t take so much mud from the river bank, and are also very easy to clean after a long fishing trip
