This is my preferred nymph line for European-nymphing. It is a level 0.022" diameter line, which is the thinnest diameter that is legal in competitions governed by Fips-mouche rules. It's micro diameter and weight eliminate sag in the guides when European-nymphing, which increases strike detection. It also increases the range in which you can successfully attain a natural drift.
