I'm experimenting with this one at the moment, which links the latter part of the SDW from just before Chanctonbury ring to the point where it drops into Shoreham by Sea, with another favourite of mine, the route from North Stoke to Arundel, although I'm going to try following the River Arun rather than crossing the valley between North and South Stoke. All in all it will be a 40 mile ride which would either make a great day ride introduction to the South Downs or a good basis for a sneaky overnighter.
Sorry, I missed the requests for the route.
This is the one I followed:
