"Our club teams are going very well so we've got to feed how they're playing into the mix," said Heaslip. "We've got a lot of Leinster players but Munster and Ulster have also qualified for the last eight of the Heineken Cup.
"We just have to bring that form and that blend of styles into the national side and hit the ground running against Wales. You can't win the Six Nations in the first week but you can lose it."
