Re: Question Re: Transition from Back to Forward cast
Yes, when making short - most trout casts - you want your back cast to completely unroll, especially if you're casting two flies and/or an indicator.
When making long casts - many saltwater casts - you want to begin your forward cast before the cast unrolls. The fly line will be in the shape of a sideways candy cane.
To do this you'll have to look behind you, without rotating your shoulders farther back, and watch your fly line unroll. This is what all tournament casters do.
If you don't do this the fly line will start to fall with slack in it and you'll probably end up hitting yourself with the fly. Even worse, when the fly unrolls it might bounce and add a lot of slack to the line.
