LEARN THE ROLL CAST
Because our line is ushered towards us using a raised rod (diagram 4), it makes perfect sense to roll the line out, either back onto the water or into an overhead cast. When facing upstream, simply let the line drift past you to form a D-loop before tapping the rod forward as normal. If you’re angled downstream then the current’s pull won’t necessarily allow a D-loop to form. This is best done now by pointing your rod behind you, before bringing hand, arm and rod into the usual forward delivery position.
Tracking flies back towards you by raising rod naturally forms a D-loop ready for roll casting.
