I'd put Horne to 12 to smash Steyn again.
I'd also play Crawford at 14 over Alofa for the kicking game, we're going to need it for the next 2 matches.
Alofa or Betham? I'd play Crawford on one wing and Beale at 15 also, but as to which winger goes out, well its a really tough call. Both are playing very well, Betham is probably a better blindside winger (see his try last week) but Alofa has a magical step that is very hard to stop. I'd probably go with Alofa, but I wouldn't argue either way.
I agree for Horne to terrorise the 10/12 channel. They will have an inexperienced 10 and we need Hooper to terrorise their new 10 with his speed to the ball to force him deeper into the pocket and Horne on Steyn.
I hope we go with Robinson, TPN, Kepu, Douglas, Potgeiter, Hooper, Dennis and Palu. Skelton can come on for Palu after 50-60, with Potgeiter going to 6 and Dennis to 8. If the Sharks can get on top of that pack good luck to them.
My only reservation is the set piece. Scrum and lineout have not looked good all year and from the look of it we will have a young and inexperienced SA ref for what will be a key match in a very difficult location. That could get very ugly; I hope the message about the appearance of objectivity has got through from the machinations of the last few weeks. Pity Joubers has the Bulls/Chiefs game and couldn't have been swapped, but that will be a key game too.
