Much of England's team sheet writes itself, but there are still a couple of areas for debate.
I'd like to see Edwards and Knight open the batting, looking to reprise the show they put on in the 1st ODI at Scarborough, where they got England off to a flyer, playing quality cricket shots which delighted the crowd and the scoreboard!
Then I'd call for Wyatt to bat at 3 - she might make runs or she might not, but she has been in fantastic form this year, and as an added bonus you know the one thing she won't do is hang around. (But in reality I suspect Taylor will pull-rank and bat at 3, regardless of anything else!)
Assuming the selectors invoke the 'class is permanent' clause in the case of Lydia Greenway (who has not had a great season) the only other question is Winfield or Beaumont? I think TB scores too slowly to ever be an international T20 player, so "Moose" (Loz Winfield) it is then!
Bowlingwise, England will want to play Brunt and Shrubsole if they can, though if both play all 3 games it will be something of a miracle! The real dilemma is whether to play spinner Danni Hazell, who hasn't been showing the same form she did when she starred in last summer's Women's Ashes, or slow-medium left-armer Natasha Farrant, who could do a very similar job of drying-up the runs. My pick would be Farrant, and I think the selectors will agree with me, partly because England clearly see Farrant as "The Future" and will want to give her some cricket this summer, having sat her out of the Test and ODI squads.
So, here's my 11:
