Let's do the match-ups, shall we?
15: Rob Kearney vs Lee Byrne. A very marginal one. Neither have shown their 2009 form yet both have improved as the season has gone on. I'm going to call this one a tie.
14: Shane Horgan vs Tommy Bowe No question here, Ospreys
13: Brian O'Driscoll vs Andrew Bishop Bishop will have to play exceedingly well to get one up on the maestro. Leinster
12: Gordon D'Arcy vs James Hook Two international centres, neither at their best. I know who'd I'd rather have in my team though. Leinster, barely
11: Isa Nacewa vs Shane Williams Isa Brings the better kicking game and might be a little stringer in defence, but there's only one ickle Shane. give him the ball and he'll score. Ospreys
10: Jonathan Sexton vs Dan Biggar The two most promising 10's in the British Isles. Sexton has proven himself at the highest level, Biggar hasn't. Leinster
9: Eoin Reddan vs Mike Philips Despite beind the standout performer in Ireland's 2007 WC disaster, Reddan hasn't featured much on the international scene as of late. We all know what Mike Philips is capable of. Ospreys
1: Stan Wright vs Paul James One of the most underrated props in the game versus erm... Paul James. Leinster
2: John Fogarty vs Huw Bennett While neither are world beaters, the Welshman is a far more capable player than his enthusiastic but lacking opposite number. Ospreys
3: CJ van der Linde vs Adam Jones CJ is the better prop, but I can't see him lasting the full 80 minutes if Leinster need him. For that reason, I'm calling it a tie.
4: Nathan Hines vs Alun Wyn Jones The second row is certainly going to be a battleground on the weekend. I believe Hines has more fighting qualities than Jones and is a tougher operator overall. He may be liable to pick up a yellow though. Leinster
5: Malcolm O'Kelly vs Jonathan Thomas Two experianced players, Thomas however is still in his 20's. Ospreys.
6: Kevin McLaughlin vs Jerry Collins Rocky who? The Leinsterman has really filled the pretty gaping void left by Elsom this season. That said, Collins is one of the best 6's of the modern era and will prove a good test for a man hoping to prove himself down under this summer. Ospreys
7: Shane Jennings vs Marty Holah I'd rather have Jennings in my XV. Leinster
8: Jamie Heaslip vs Ryan Jones A man who hasn't fired on all cylinders since 2008 comes up against possibly the best 8 in the world at the moment. No contest here. Leinster
The Benches
Neither is particularly impressive. I'll call it a tie.
The Coaches Cheika has revolutionised everything about Leinster rugby. We're on of the lowest scorers in the league yet we have the most solid defence, unthinkable a few years back. Leinster
In total that'a 6 Ospreys, 8 Leinster and 3 ties. Should be close enough if the game was solely based on my valuation of the squads.
