Tomorrow's Happy Valley Triple Trio looks as tough as they come with, perhaps, the seemingly well handicapped Diamond King banker material in the third event, which opens the popular exotic wager. The David Hayes-trained galloper ran to marks in the mid 60s in the first half of last season but is now down to a rating of 42. He has the advantage of a run under his belt, when he ran a fair third, and so often at this time of the campaign, the benefit of an outing can tip the balance. Six-time champion jockey Basil Marcus is in the saddle. Right On ran second over course and distance first-up this season and is another to respect. David Oughton's team habitually need their first few runs but his Cossack has been moving as fluently as ever in the mornings in readiness for this and also appeals as down to a competitive mark. He could well place, as may Race To Honour down at the bottom of the weights. Just For Pleasure appears to have thrived since moving to Brian Kan Ping-chee. He has more than enough ability to add another victory to his Class Four success at the backend of last season but could just be found out by the mile first-time-out. Star of Wah Yan is a similar case to Cossack in that he's handicapped to at least place. Good Putt can improve on his win of last season and could go well at reasonable odds, despite having had a few problems in transit at the Valley before. Bruce Hutchison's Lucky Glory could be the one in the fourth event. He's another down to a very attractive rating, he's had the benefit of a run and he goes well over the Valley mile. Grand Vefour loves the Valley mile and must be considered on that basis while Nansen should be suited by Class Five. Sincerity is a consistent type who should lead and can do so with the benefit of the promising claimer Vincent Sit taking 10 pounds off his back. He would be a viable alternative to Lucky Glory as a banker in this middle pin. Mighty Prince appears to have improved for Wong Tang-ping and is worth throwing in, as is Super Conqueror, who should strip fitter for his first run back. Bill is a pretty straightforward choice as banker in the final leg following an improved debut effort when second to Helene Treasure in a tougher race than this. He, too, has Sit claiming 10 pounds and, as a most progressive type last season, is hard to ignore. Top Light, Daring Steed, Cash Fortune, High Powered, Shining Winner and Johnny's Angel are others to watch.
