I think we did them twice in 2012-13 season. Indeed I think we won 5/6 interpros that season, only losing to Munster away from home.
The Nevin Spence effect????
That was the year we "won" the league, but they introduced play-offs and we lost the one that really mattered against Leinster in the final.
We had home advantage for the Final, but due to Ravenspan being redeveloped and not yet up to full capacity, we had to play our home final at Our DS.
Definitely don't want history repeating itself vis-a-vis Leinster this season.
