Reds had a good description about lines for switch rod fishing: http://www.redsflyshop.com/blog/fly-rods-and-fishing-gear/why-switch/ For indicator fishing they note the Rio Switch and the Aiflo Speydicator. they note that Scandi heads are not good for indicator fishing but are good for other things. "Fortunately both Rio (Switch) and Airflo (Speydicator) have a specifically designed line for indicator fishing and moving all the junk to the proper line for the drift through the bucket. These lines will cast that junk much easier than any single handed rod and then mend with the ‘longer lever’ much easier and further than any single handed rod. While they will not turn over long heavy tips and dead chickens like a Skagit line, I always have a fast sinking poly leader in my wader pocket that loop-to-loops on the indicator line and will swing reasonable sized flies below the surface.'
