Paul Nolan is excited about the prospects of See U Bob and Cuan Na Grai in the Arthur Guinness Galway Hurdle.The latter won the 2006 renewal and has rediscovered his best form in recent outings."It's hard to split him and See U Bob, the weights going up hasn't helped Cuan Na Grai, though," said the County Wexford handler, three times a winner of the race since 2002."In saying that the ground is more of an issue. It hasn't cut up, though, and as long as there is not too much more rain we won't be using it as an excuse. Ideally, See U Bob's best runs have been on better ground too. Both horses have a chance but Cuan Na Grai's experience might just give him the edge."Cuan Na Grai is finally back in the same sort of form as when he won the race and he has never really had his ground since that day. But as he's had a leg, he probably wouldn't want it too quick now."He's already won one over fences but there just wasn't a suitable race here for him so we've taken a chance, but he'll certainly be going back chasing."
