Hi Simon, I no it may be a bit late for this reply but having been to Brands on the last BSB round I found the following great for shooting with a 300mm lens
Over the bridge inside Druids - Fantastic
Westfield (on GP Circuit) Fantastic
Sheene Curve going into Sterlings -Fair but gets busy, good for reverse shots coming out of Sterlings with 500mm lens on
Hope this helps in the future fella.
Ian
