The amount of line you can throw behind is dependent on the amount of space behind. If there is fifteen feet clearance behind you can throw a fifteen foot belly of line behind - that's thirty feet of line you are moving forward. This dynamic roll cast blends all the way from the static roll cast with the line hanging straight down from the rod tip two feet behind your ear to a full blown power roll with not much more than the leader and a little bit of line remaining on the water. The amount you throw behind depends on how much room there is and how far you want to roll cast. The Spey cast is a variety of dynamic roll cast or the dynamic roll cast is a spey cast in a straight line. This cast is very useful fishing and for hitting targets in accuracy games. Try to keep the back toss as close to your body as possible without fouling. It works fine on the off shoulder also. You can get just as much power on the off shoulder when the line is down stream on that side or the wind is blowing from your dominant side. Try it. You'll like it.
