[Versión en español]
By increasing the flex in the rod, we increase the velocity it imparts upon the line. We can do this by aerialising more flyline. We can also do this by applying more power to the stroke. Either way, as soon as you increase the flex in the rod, you must increase the size of the casting arc to accommodate this, otherwise you get a tailing loop.
When you try this think 'heavy' not 'fast'. Stop hard into the backcast. And let it fly on the forward shoot.
Remember to retrieve that shot line back in again afterwards.
I got Karen to practice a few roll casts and then the sequence (roll cast, false cast, shoot).
And then it was time to face the wind….
