I'm with N-Bomb on this one, Brownlie would be the only guy I would be looking at dropping, myself I would also be looking at Papps as another option, in at 3, Taylor & Williiamson dropping one place each. (If I was bring back Guptil I'd probably do the same).
In saying that I'd probably be sticking with the same XI going to England, give the team a chance to gel with a steady XI and see if they can continue to get better.
