We have been using 1 Dyneema cable @ Bowland Forrest
for the
past 12 Months - on grass with rubble hardned tow out
track

After initial teathing troubles - Finding the most
durable cable
manufacturer and modifying linkages and shock ropes
etc it has
now settled down and we have converted both drums to

Dyneema.

The cable lifts free of the ground as soon as tension
is put on it
therefore wear and tear on the ground is minimal either
at cable
retrieve or launch

Launch hight are regularly 200ft higher than stranded
steel cable
and there are significantly less cable breaks.

Care has to be taken not to land across thc line of
cables as the
cable can stand above the surface of the grass especially
in dips
or hollows or when the cable is under any kind of
load - ie cable
retrieve - hand pulling of cable to obtain slack to
attach to a
glider etc. (This is potentially far more hazardous
than steel
which tends to bed into the grass.

Also worth noting is the potential for the cable to
fly in windy
conditions - so care must be taken on the retrieve
to make sure
cables do not cross and that a very large seperation
is used @
the departure point.
