It's a real shame that we lost the one day to rain. England (notably Vaughn) batted well to avoid the follow on. The question now is what target to SA set England?

That's one for you spaw. SA are about 270+ runs ahead. There is less than one days play left. If SA want to win the game, they need to declare (i.e. stop batting and say they have made enough runs) but if they were to declare too early, England could go on and make enough runs to win the game. Would consider that the game is going for a draw and just use "batting practice", would you try to set a "sporting total" and risk loosing, would you make sure you are so safe that you can't loose but also know that the chances of bowling England out in the remaining time are about nil (it's unlikely even now)?
