IRELAND coach Phillip Doyle has spoken this week about the importance of this year's Six Nations in terms of the 2014 World Cup qualification.
He has made two changes to the collection that easily beat Spain 39-7 out in Ashbourne two weeks ago, scrum-half Larissa Muldoon and flanker Laura Guest starting.
There are enough experienced players to give Ireland confidence that they can go to Aberavon with winning on their mind.
"Qualification for the 2014 Women's Rugby World Cup is dependent on the result from both this year's and last year's Six Nations so we will be looking to raise the bar again this year in terms of our performances," said Doyle.
