Here is the rig that Brooks Leffler constructed for me, under pressure, since it was a deviation from his normal Picavet suspension rigs.  I am very happy with it so far but have a lot to learn regarding aiming, composition, controlling the rig in general.  Note the shock absorber on the top of the pendulum for damping fore and aft movement.  This idea was "borrowed" from Craig Wilson.  Also, note the two fins, or dihedrals.  The use of these was after a design used by Christian Becot of France.  Details on this feature are available from Christian's article in the Aerial Eye, Volume 4, Number 2, page 14.  Brooks' wonderful workmanship and attention to detail make this rig a real pleasure to use.
