COLOURS Hero put up the kind of run for defending champion trainer John Moore in yesterday's second event which suggested he could help Moore defend his title against the onslaught from Patrick Biancone and Peter Ng Bik-kuen. But with one proviso. Colours Hero looked a bit one-paced as he plugged on gamely to be fifth to Bayview Boy in a fast-run 1,200-metre sprint. If he is to prevail then he will almost certainly need farther. Yesterday's run should have done him a power of good and a move to a mile or even farther is likely to see him reveal his full potential. But a word of caution about Moore's Send A Signal who was well backed to make a prominent showing on his debut in this but could only finish ninth of the 11 runners. He had worked very well going into the race but looked somewhat reluctant during proceedings and, while it could be a premature judgement, he may not be one to trust implicitly. A watching brief is advised - not least as he returned with a heart irregularity. Ivan Allan has a ready made winner in All Thrills who looks far too good for Class Three on his tenacious, short-head second to the highly-promising Namjong in the third event. All Thrills became a little unbalanced when asked for an effort 300 metres out. Third-placed Diablo, now fully acclimatised, can also be followed.
