Agreed, would be a great chance to see them in action. I'm just a little bit cautious of taking Japan too lightly, plus good chance to stay match fit and build on combinations.I was thinking just a chance for Rennie to see them in action. But sounds like he gets a very accurate picture at training, so maybe you're right.
I'd go with something like
3. AAA (c)
12. Paisami (assuming SK isn't fit)
Leave Slipper, Hooper and Thor on ice for the three UK games
