FuzziOn is correct with his comments - I will just add that the old circuit was 2.61 miles, but the current version of the track is 2.47 (from memory). The changes were made to increase run off.
I was a bit disappointed that the pedestrian bridge before the Druids Hairpin didn't have a different look - I'm sure it didn't say Palmer - I'm pretty sure it said Dunlop years ago.
The track itself is, I think, a better, more flowing layout in its older configuration so I think it will be popular.
