Here is some nice slow motion Spey Casting by Jay Nicholas and his buddies somewhere on a river in Oregon: Jay is a Renowned fly tier, writer and fisherman who writes for The Caddis Fly: Oregon Fly fishing Blog He also has his own Website called Fishing with Jay.
Jay is also featured in a boatload of fly tying videos like the one below. He is humorous, talented and makes it look easy. I try to stop in at the Caddis fly shop in Eugene whenever I can and pick of some of his flies…He has some of the gnarliest, fishiest looking Intruder type creations I have seen as well as many that could be described as Non gnarly and elegant works of art. They are irresistible and I’m sure the fish like them too.
