I've never taken any notice of the facilities tbh, we've ALWAYS had decent terracing be it sleepers and dirt or the concrete of today, that is all you need to watch the racing. I guess when Huggy was doing the track it was early days for Buster, before the stocks really took off, Huggy was a master and had good material to use. Huggy kept grip the track over.
Buster has to accommodate modern day bikes that hate grip but if riders have the will and skill to have a go now they can gain ground and pass, and that is gooooood to watch
