Spey Casting Mechanics: Not As Hard As It Looks

“The line’s contact with the water creates an ‘anchor’ that halts the backcast’s momentum and creates tension, bending or loading the rod with energy that is transferred into the line on the forward cast, as the line is ripped off the water and propelled forward. No behind-your-back backcast, yet the 180-degree principle stands.” John Hayes does an excellent job of describing the mechanics of Spey casting in the Pittsburgh Post-Gazette.
