Most of the fellows over here will use some sort of a sink tip system off a Skagit or Scandi type head. One option that I've found to work a treat is to take what's (for a lack of a better term) a full sinking head (RIO and Airflo -others?- make them) and just attach that to the shooting line.
These come in lengths as short as 15 feet to as long as 30. Takes a bit of 'practice' with your stroke timing, but the longer ones behave much as would any tip system line. The shorter ones are a more gentle 'touch and go' with the cast.
The end game is these shoot out like a rocket(!) and sink like a brick. Once these hit the water 'mending' is close to a dead issue so a 'air mend' when the line is moving out over the water is needed.
The other 'good thing' is, given the heads are so short, there's very little to do to roll one up to the surface for your next cast. The 'down side' of this system is .... you'd better like stripping in all that shooting line behind the head ...... there will be a lot of it.
