This is a popular pattern for steelhead in the GTA and on Great Lakes tributaries throughout the region. Can be euro-nypmhed, fished under an indicator or float fished with a centrepin.
This is a handy addition to a euro-nymph collection. If you don't fish euro-style, not to worry, this prince nymph variation works just as well presented below an indicator.
Perdigon variants in multiple colours are a great go-to for euro-nymphing in both local waters, and those further afield. Tungsten gets you down quick and the glossy body has the extra bit of flash to get the trout's attention.
