Mark,
Fairway had won the Champion Stakes over 2000m 6 months before failing in the Guineas so I don't think many people put his Guineas failure down to " couldn't get the trip ". If memory serves me the track was cutting up a bit and he was taken on in front.
Got his own way on a dynamite leaders track at Randwick in the AJC Derby and won the 2000m Turnbull as a 4YO.
Bel Esprit is an out and out sprinter in my view. The Show Day Cup winners that were 3YO's all went on to prove themselves over a bit more ground. If you don't think BE will get a good mile don't back him on Sunday.
Caulfield was a swoopers track last time around too so that plays against him a bit.
