The NSW Waratahs and Western Force are leaving little to change, even with their Super Rugby AUS Grand Final match-up locked in.
With both teams undefeated in the competition, Sunday's match at Pittwater Park will decide the all-important hosting rights for next week's decider.

The two teams played in last year's Grand Final, with the Waratahs defying the travel to secure the inaugural competition.
A Force win would require them to repeat these heroics, while a Waratahs win would very likely send the Force on a back-and-forth trip to avenge that defeat.
Wallabies Miles Amatosero and Dylan Pietsch return for their respective sides, whilst the Force will call upon Australia Sevens star Aden Ekanayake via the bench.
Waratahs coach Lachlan McCaffrey was eager to see how his side was tested by the strong Force team, who have also called Misinale Epenisa into their starting pack.
"I think some of their key players and more experienced players have shone in the last two weeks," he believes.
"Guys like Nathan Hastie, Kurtley Beale and James O'Connor....You put four or five really experienced Super Rugby players in a Super AUS team, and they stand out and help those younger boys excel during the game.
"Defensively, we're going to have to be ready."
Force coach Damian Steele acknowledged the unique situation but understands the importance of delivering on the weekend.
"It's an interesting one but I think for this weekend as well, knowing that the winner gets to host is a big carrot as well for both teams," he said.
"Both teams will obviously be going out to do their best to win this one so they can host and not have to travel the week after.
"We've got a couple of changes again this week to the squad. So it's not about trying to get too clever or too tricky or too different because we are having guys in their first run with us."
The return of Pietsch was particularly motivating for Steele and the Force, picking up a foot injury during the tour of Argentina.
"He's obviously a wonderful asset for us to be able to utilise in this competition. He was pretty keen last week and had to get held back there," Steele revealed.
"He's super excited. He brings such a physical presence and a huge work rate, and he brings great energy amongst the squad and in the change room. It's great to have 'Peachy' back and we're looking forward to having him out there on Sunday."
