Telefonica remain further north along with Abu Dhabi, while Camper has opted for a southern route, looking for long-term benefits.
Team New Zealand helmsman-trimmer Rob Salthouse said while the team appear off the pace of the leaders now, he believes they are well-placed to make gains later in the race.
"Not a lot of nerves from our side of it," said Salthouse.
"But I can understand why the other guys have done it, sort of tried to sail in flatter smoother water for longer and use the breeze that was on the shore.
"Their trouble will come a little later on when they try to get east and they'll struggle - it's normally the key to heading north up the Indian Ocean.
"They may have it right at this time, but it's not telling us what we think it should be."
Telefonica navigator Andrew Cape said it was time for a gamble, having played the tricky shifts they were constantly dealt as they sailed around the bottom of South Africa since leaving Cape Town last weekend.
"Really it's a roll of the dice, and you place your bets," Cape said.
"It is tense... but I'm confident as well."
