Balance and finding it will be key for Australia and New Zealand as the two teams kick off their campaigns in the ICC Champions Trophy 2017 match on Friday.
The Trans-Tasman rivals will want to get off to the ideal start, and in order to do that, they will need to get their playing XI right.
Both teams have plenty of options to choose from, but choosing the right ones for this game at Edgbaston might not be that easy.
Australia, for instance, have four world-class bowlers in their lineup in Mitchell Starc, Josh Hazlewood, Pat Cummins and James Pattinson.
However, to get the right balance, one of the four, at least, might have to sit out, and that looks likely to be Pattinson.
If Pattinson does miss this game against the Black Caps, then Australia will need to decide on selecting a bowling all-rounder – John Hastings – or a batting all-rounder – Marcus Stoinis or Moises Henriques.
Stoinis is more of a match-winner and Henriques is a solid option with the bat, but Australia won't want to leave themselves too short in the bowling department, so Hastings could get the nod.
Of course, if Steve Smith feels the spinners could be more effective, the skipper might choose Adam Zampa, even if the captain has part-timers in Glenn Maxwell and Travis Head.
Chris Lynn, after his brilliant exploits with the bat for KKR in the IPL as an opener, is expected to be in the playing XI, but what will be interesting to see will be if the big-hitter starts at the top of the innings or comes lower down the order.
Australia have a strong top three in David Warner, Aaron Finch and Steve Smith, so it would be a bit of a surprise if they tinker with that.
New Zealand do have a decision to make in their top order – whether to go with Luke Ronchi or Tom Latham as Martin Guptill's opening partner.
Latham has been in terrific form, but Ronchi has been a mainstay in the New Zealand lineup. The Kiwis could also drop Neil Broom and play both of them, with Ronchi coming down the order.
While Tim Southee and Trent Boult are expected to be a part of the playing XI, especially considering the English conditions suit these two swing bowlers well, the decision for the third seamer's slot will be between Adam Milne and Mitchell McClenaghan.
Colin de Grandhomme is another option, but with Corey Anderson and James Neesham expected to play, will New Zealand go with a third all-rounder?
Expected playing XI:
Australia: David Warner, Aaron Finch, Steve Smith (C), Glenn Maxwell, Travis Head, Chris Lynn, Matthew Wade, Mitchell Starc, Pat Cummins, Adam Zampa, Josh Hazlewood.
Players missing out: Moises Henriques, James Pattinson, Marcus Stoinis, John Hastings.
New Zealand: Martin Guptill, Tom Latham, Kane Williamson, Ross Taylor, Corey Anderson, James Neesham, Luke Ronchi, Mitchell Santner, Tim Southee, Mitchell McClenaghan, Trent Boult.
Players missing out: Neil Broom, Colin de Grandhomme, Adam Milne, Jeetan Patel.
