Before you do the benwick, road which is the b1093, try the b1095 from stangroung to pondersbridge, its on the map for the benwik route. (stanground to pondersbridge on the b1095) give it a go. it has good straights to get good speed. Ive live next to the road and i see bikes at the weekend getting a good pace down there. the corners are great and some are sweeping. Not many hazards, just the odd side road off into the sticks. give it a go. great road for the summer.
A very short route with some very intense twisties, well worth a look if you're in the area. To be avoided during commuter periods as it is quite difficult to pass on this section
