Roll Cast Pick-Up -- Used with heavy sinking lines,,,,roll cast with the Lefty Kreh method,,,,,,rod horizontal to the rear, cast forward as normal (stop at 11:00 not with rod tip stopping down at the water as usually taught) the line will be pulled up to the surface and allow a conventional back cast. This may require two casts to bring up an extra fast sinking line to the surface. If used with floating or intermediate line, the line will be completely above the water's surface at the completion of the roll cast pick up,,,,then a back cast,,,,shoot line,,,,, and a forward cast is made. The objective of the roll cast pick up is to set up the line for a conventional back cast. Spey casters are very familiar with shooting line from a forward roll cast however, single handed rod casting techniques teach a very inneficient roll cast.
Water Haul - Old saltwater technique with heavy full sinking line, normally used when fishing from a boat. Make a roll cast pick up,,,,then back cast and allow the line to just touch the water,,,,the rod is now easily loaded into the single presentation forward cast. This minimizes any false casting with a heavy sinking line, one back cast,,,, water haul the forward cast to final presentation.
Change of Direction Cast (up to 90 degrees) - Another technique taught by Lefty Kreh. RH bank, fly is downstream,,,point rod at fly,,, rotate hand and reel 180 degrees clockwise (reel pointed at sky, rod is still pointed at fly, ref. Galway Cast with thumb on bottom) make pick-up (back cast) parallel to river,,,,when rod is vertical rotate wrist 90 degrees clockwise and change cast direction toward middle of river (90 degrees to bank) now complete the forward cast as normal. You have just made a 90 degree right angle cast in one continous motion.
