HH - couldn't agree more.
Maybe an ATZ just to control the air over a congested area, but PPR/Extra helilanes etc is a waste of time of Epsom.
The CAA are almost always at these events (or at places like Battersea 2 years back during Silverstone)
The London zone will get more traffic from Silverstone than it did for Espom.... and no PPR /extra Heli routes.
Roll on Ascot eh?
