Triple Trios don't come much tougher than this Friday's exotic wager. The final leg, a Class Four, 1,800-metre contest for which Ivan Allan's improving last-start winner Quick Speed looks a standout banker, is the easiest of the three races. But the big problem is going to be getting to this sixth event with hopes still alive as the first two legs have a decidedly impenetrable feel to them. Quick Speed held on bravely last time from Senator over 2,000 metres at Sha Tin, the bob of the head going his way in the photo. Quick Speed, a son of Just A Dancer, had turned for home positively jogging under Basil Marcus and appearing set for a fairly comfortable success. Yet, in the final 50 metres, his stride shortened and the drop back to 1,800 metres on Friday could well be in his favour. That form has also been franked by Senator's subsequent Happy Valley success. The big improver could be Wylie Wong's Aly Baba, who has always looked a fair staying type in the making. He ran on promisingly on debut when badly checked at the start under his inexperienced female rider, who then lost an iron. Despite that mishap, he was noted staying on well over the concluding stages and he should relish the move up in distance. Since that run Aly Baba has trialled strongly, too, again doing all his best work in the final stages which suggests he's a future staying winner. Mount Sapphire has very solid recent form and has to be considered, while Brian Kan Ping-chee's Bordeaux is another potential improver. He's a thorough staying type in the making and has been moving strongly in preparation for this. Golden Phoenix is worth watching as he's yet another who has shaped as if he's been looking for this kind of trip. The Class Six third event, which opens the TT, is about as competitive as they come. Felix Coetzee is back on board Money For You, who has had plenty of excuses of late, while Win Label is very well rated these days and should improve for the drop into the bottom grade. Others to note include form contenders Owners' Success, American Star, Winford and Ming River. The newcomer, Helene Honour, could be the best banker in the fourth, the TT's middle pin. The Ricky Yiu-trained import had smart form in Australia and has impressed in everything he's done in readiness for this. Floral Regent had good form in Ireland. His debut run here can be forgotten as it was on the dirt. Monza is in a much more suitable race and could surprise.
