The UK mod. also reduces the max. permitted all-up weight so reduces
landing fees at some airfields and some regulatory costs.

If you are running on three bungees and are not flying near max all up
weight (not crop spaying) then its worth considering only using two
bungees (approved in England). In England we only glider tow with
Pawnees.
At light weights the shock units mostly never open so all the landing
load/bumps are transferred direct to the airframe through the closed
shock
unit. Its also easier only putting two bungees on.
