Good route from Oxford to Saffron Walden/Cambridge

[OliilO]

I'm likely to be driving from just outside Oxford to Saffron Walden sometime on Friday afternoon in my new toy and would welcome any recommendations for roads with some interesting driving to take on the way. I've previously been along Bicester-Aylesbury-Luton-Royston-Saffron, with only the Royston to Saffron bit being especially interesting (I'd be happy to go that way again).

So your best local knowledge please!
