THE ULTIMATE BOMB is the only runner in the race with experience and that should stand her in good stead. However, even with the aid of her rider's 4kg allowance, she's unlikely to play a leading role on the evidence of her debut display. The betting will provide a guide to the chances of the newcomers, so monitor the exchanges and follow the market movers. GRAPES OF WRATH is of particular interest, as the half-sister to Charles Dickens, along with well-related NOBODY'S PERFECT who is bred to be precocious. LUCY'S WORLD and DE GULDEN are others to note on debut.
