Hi car knocker
If you and your wife are strong climbers, then you could do Wolverton to save some backtracking. Keep in mind that it is very steep though. Its considered one of the hardest and steepest climbs in the area. I've never actually attempted it so I can't comment on traffic or the condition of the road.
Whichever route you choose, i hope you enjoy the ride. let us know howit goes.
