Ok, it's a few years old but every bit as relevant now as when I released it and has proven to be hugely popular - the Roll casting introduction from our Fly Casting DVD "Casts that Catch Fish"
I can't over emphasise how important this cast is. Deceptively simple, the Roll Cast is the most useful and versatile cast there is - more so than the fundamental overhead cast that is so synonymous with single handed fly casting.
This cast will save you hours on the stream, it will allow you deliver a fly like no other cast, it is stealthy, accurate, incredibly versatile and is a far more efficient and effective method to present a fly than any standard overhead cast.
If you have designs on learning a few casts for the two handed rod you'll get nowhere until you've mastered a good static and then a dynamic roll cast. Every Spey cast is a derivative of the roll cast.
All that fancy two handed wand waving is simply one setup move or another that forms the precursor to delivering a roll cast.
If you like what you see here, consider grabbing the full vid' here - there's heaps of in depth content on the DVD and a ton more presentation casts that really will help you catch more fish.
