I very nearly bought some Cambridge last year (was virtually in the truck when family issues stopped me)
Can't comment on breed but the society man is a very approachable chap, very easy to chat to & will see you right. I have his details if you wanna PM.
Have you considered lleyn?? Not quite as prolific (a good thing most say) easier to source, and keep that all important white face!!!
Could you send me the details please? might be worth a chat.
