Agree about the A507 being the highlight, but, I could leave the rest out.
Bit of a mix. Some nice twisty bits, A507 is the highlight, and sections of fast A road. A few pubs on the way and a couple if petrol stations to fill up at. Best done late morning or early afternoon to avoid any slow traffic. The A507 is very smooth and the rest of the roads aren't bad at all. Very little Police presence so far.
