Both Jamie Heaslip and Josh Strauss have been crucial for their respective sides this season, and both will have a major say on who lifts the RaboDirect PRO12 trophy aloft.
Heaslip, 30, has a bulging trophy cabinet and has made himself indispensable to the Boys in Blue since making his debut in March 2005.
He has amassed 70 international caps - five of which have been for the British & Irish Lions - and with Leinster he has won the European Cup on three occasions and the RaboDirect PRO12 twice, most recently last season.
Despite his international commitments, he has turned out for Leinster ten times in the RaboDirect PRO12 this season, and he has a habit of producing his best in the knock-out matches - last season he was on the scoresheet in both the semi-final and the final.
- 4 days to go - Leinster have won their last four matches to book their place in the RaboDirect PRO12 final since losing to the Ospreys on April 11.
Strauss meanwhile, has been just as influential in guiding the Warriors to their first ever RaboDirect PRO12 final this season.
The final will be the South African's 20th RaboDirect PRO12 match of the season and he too has a tendency to deliver when it matters most.
He scored his only try of the season to date in the Warriors' 22-5 victory over Munster in April which provided the catalyst for Gregor Townsend's men to arrive at the RDS on the back of a nine-game winning streak.
He was named man of the match in that game and he will be hoping for another stand-out performance this weekend.
