Interesting boopa... they're certainly two horses coming at this race from different angles. Thought I'd have a look at previous winners and see which ones I consider 2 milers UP IN TRIP and which I consider stayers DOWN IN TRIP and if anything is a 'trip specialist'
2 milers
Un De Sceaux (2017) definitely in this camp, 2 miler than stayed the trip and oozes class.
Stayers
Dynaste (2014) went off 3/1 fav - I'd say he was a stayer than dropped back and won this race because it was a weak year! He was second in a JLT (then Jewson) before going up to 3miles at Aintree for that Grade 1 and winning as a novice, (after also winning the Kauto Star - then Feltham).
Imperial Commander (2009) - Not going to look in to this too much as I've had enough now (have gone back from 2018 to now despite this being early in the post) but won a Gold Cup so clearly can be classed as a top class stayer.
Intermediate
Vautour (2016) his two standout races are the Ryanair and JLT - he had one try and 3m and emptied out to be caught very late by Cue Card. He had the class over 3m but impossible to say he was a stayer - for me he was a trip specialist, although did win the Supreme over 2m (but in the style of a horse that would get further)
Balko Des Flos (2018) has had 5 runs at 3m - form 54324 (Albeit some of that is good form) but if you look at his record at 2m4f or 2m6f it reads form 1713F312314 - so 4 wins at less than 3m but over 2m. He could prove me wrong by the end of the season but for now, he's here on merit.
Uxizandre (2015) is closer to being a two miler than 3 miler but did win 1 hurdle race over 3m1f. However he won a Schloer Chase on the way to winning the Ryanair that season. He got a great ride that day, DOn Cossack who would be firmly in the stayer category was only 3rd that day... the 'pick' of his form would have been this race though?
Cue Card (2013) - hard to pin down really to a trip as he was on the go for so long and good enough to compete in Grade 1's all the way through. Won a Champion Bumper and went off 7/4f for the Supreme over 2m, won a Ryanair the year after being beaten by Sprinter Sacre in his Arkle, kept getting beaten in the King George before winning it against Vautour and fell when in the mix in a Gold Cup. Can have him in any section, anomoly?
Albertas Run (2010/2011) - Won this race twice, easily his best form and therefore confidently in the Intermediate section.
Riverside Theatre (2012) - Was a 2 miler for a long long time but then won 3 grade 1's on the spin at 2m5f (ending with his Ryanair) so very hard to say that wasn't his best trip too?
Impossible to really know if "best trip" is fair, because better horses were either running at 2m and 3m2f in every single edition of this, so we'll never really know.
In terms of Monalee and Min, neither have yet proved what there best trip is. Min has stuck to 2m in the main and is clearly at a very good level - I think this year they'll explore him UP IN TRIP and it could see him pick up a win in this race.
Monalee has been running at 3 miles and is also clearly at a very good level. I don't see him excelling at any further, so a STEP DOWN IN TRIP may well see him pick up this race.
Impossible to rule either out despite their different paths in my ever so humble opinion.
