VoiceFollower help

[James E. Bailey]

I'm having two questions.

First, \override VoiceFollower #'style = #'dotted-line doesn't seem to work here. Why not?

\version "2.12.2"

\score {

   \new PianoStaff <<

      \new Staff = RH \relative g' {

         \time 3/2

         \showStaffSwitch

         \once \override VoiceFollower #'style  = #'dotted-line

         g4 a h c a \change Staff = LH f4 |   

         \hideStaffSwitch \change Staff = RH

         r4 c' h2 g  |   

      }

      \new Staff = LH \relative f' {

         \time 3/2

         f2 d4 e c \change Staff = RH r \change Staff = LH

         d4 c e2 g

      }

   >>

}

Second, is this the most efficient way to do something like this? It seems a bit over-burdened.
