Christophe Dominici - who booked Stade Francais Paris' place in the 10th anniversary final with his last-gasp semi-final try against Biarritz Olympique - still hurts when he recalls the 2001 Heineken Cup final defeat by Leicester Tigers.
Elusive French winger Dominici was at full back when Leicester triumphed 34-30 in a pulsating Parc des Princes final and he does not want to go through that agony again.
"We have only played in that one Heineken Cup final and we lost it," said Dominici. "If I had to choose between a French title and the European title I wouldn't hesitate.
"You know, when you don't win the French championship you'd give all your caps for the national team to get that one title.
"When you're not the European champions it's the same thing. It hurts me and hurts us not to have won it. If only we had the power to choose the titles we wanted, it would be easy to win! Sadly it's not the case.
"We know how important this tournament is and it hurts to have never won it so this year is pretty special for us as we haven't been able to get to the final for four years.
"But we will need everything we have in Edinburgh because Toulouse are such a seasoned Heineken Cup side with two titles and a third final. They know what it is like to win and to lose and whatever happens, it's going to be very tight.
"I have seen many teams lose in the final of a competition and normally it takes them a long time to recover.
"However, Toulouse lost the final last year and have come right back just one year later. That said, they were very unlucky to have lost the 2004 final.
"They went into injury time looking to beat Wasps as European champions before losing so it's going to be a very difficult game for us. Let the best team win.
"This has been a marathon month for us with three matches in the opening week and now the final of the Heineken Cup.
"It's true that we're playing with a squad of 33 at the moment and it's obviously worked since we've won our two away matches.
"
Our wins have ensured our qualification for the semi-finals and we're looking to be in a good position for them - and that's why several key players were rested last weekend in the run up to the Heineken Cup final."
While it promises to be a battle royal on the pitch, the two sets of fans also promise to make it a special occasion.
"As far as the club's efforts to get fans to the game are concerned, we know this club and the supporters who give it life," said Dominici.
"Max Guazzini wants to share this experience with as many of those fans as we can, to make it as cheap as possible to travel and support us and I hope we'll have a lot of people behind us.
"As to what happens out on the pitch at Murrayfield, if someone gave me the chance to choose between being French champion and European champion, I know what my choice would be..."
