It's impossible to review routes if there's 12 different roads in the route. So, on a whole route review I can say that this would, indeed, be one hell of a day out. Lots of twisties, sweepers, scenery and lots of fun, indeed. It would just be nicer if people didn't upload hundreds of miles worth of a dozen different roads to the site, and instead let people build their routes from roads that they wish.
