As close to objective as I can get:
3/1 Presenting Percy
A thorough stayer who will be seen to best effect on softer going. May be the next superstar and win going away but may also get taken off his feet early on. Idiosyncratic preparation. Seems a very short price.
7/2 Clan Des Obeaux
Had a good season and looked very useful at Kempton and Ascot. Not absolutely certain to stay and, being a third season chaser with 13 chase runs, would be a little against the trends.
5/1 Native River
Another thorough stayer who's already been there and done it. Looks likely to give followers a proper run for their money but win chances greatly improved by soft ground.
9/1 Kemboy
Big improver in the last year and has beaten most of the other Irish. Stamina doubts in some quarters but trainer says he'll improve for the extra distance. Jumping an issue last season but has been ok the last three times. Probably the pick on a trends analysis.
10/1 Bellshill
Like Clan Des Obeaux a third season chaser but fewer runs than CDO. Good and improved performance the last time and likely mount of Ruby. Likely bang there with a clear round.
12/1 Road To Respect
Ground against him last year but has gone down twice at Leopardstown and it's hard to see him reversing the form. Would have a big chance in the Ryanair and trainer still not ruled out that race.
12/1 Al Boum Photo
One of last season's top staying novices. Not tried at open G1 level because of the ground and possible non-runner if the going is better than soft.
12/1 Might Bite
Looked nothing like last season's horse recently and age stats very much against him.
14/1 Thistlecrack
Age again an issue and also stamina doubts.
16/1 Frodon
A little under the radar because the high rating has mainly been obtained in handicaps. Can't see it winning but an early bold show likely.
16/1 Anibale Fly
Will need soft ground and likely to find others better even then.
16/1 Monalee
50:50 this race or the Ryanair but not really gone on from last season.
Others to consider:
20/1 Elegant Escape - may run a place in a real bog.
25/1 Shattered Love - better than this season's form and the mares' allowance will help.
You're welcome.
