I trotted off and got the Rio DVD as mentioned above by Ben. So far I've watched discs 1 and 2. I'm really enjoying it. They explain lots about the casts and break down the different stages of each cast. Even dedicating some time just to getting the forward cast right. I like how they have a section explaining the common faults. The only bit I'm not too keen on is the bio-kinetics bit. I just wish I could set it up to watch it on the river bank and then have a shot at doing what they've just deomnstrated.
I know Iain got a copy too, how are you getting on with it Iain?
Cheers
Matt
