The striking cobra would be high on my list
Any of the obstacle styles of cast ie , reach, curve, puddle, steeple, etc all of these will provide great fun and be very useful.
Some of the roll casts, ie snake, single speys etc are really good to get to grips with on single handers. Some of the direction changing cast would be good too, i dont enough and certainly cant give them names, Magnus?
Really looking forward to this
