Ladbrokes reaction to Cheltenham action David Pipe's GRANDS CRUS slashed to 3/1 second fav (from 12s) for the Ladbrokes World Hurdle after stunning Cleeve Hurdle win. BIG BUCKS eased to 4/6 (from 4/7). David Williams of Ladbrokes said: "Grands Crus set Prestbury Park alight with his stunning win in the Cleeve Hurdle. The Ladbrokes World Hurdle suddenly looks a great deal more competitive and we're delighted." NEPTUNE COLLONGES 33/1 for the Cheltenham Gold Cup and the Grand National after taking the Argento Chase. David Williams of Ladbrokes said: "Neptune Collonges' win derailed the Punchestowns bandwagon. We were left scratching our heads and the odds reflect that." LOCAL HERO now 14/1 for the Triumph after taking the Cheltenham opener under AP McCoy. Runner-up INDIAN DAUDAIE also 16/1 for the Festival David Williams of Ladbrokes said: "Local Hero caused a ripple rather than a splash in the Triumph market. We feel his jumping needs to improve if he's to feature prominently in March." THE GIANT BOLSTER enters the RSA Chase market as a 25/1 chance after landing the gamble at Cheltenham. BOBS WORTH and ROCK ON RUBY share 5/1 favouritism for the Neptune after fighting out the finish to the 3.05
