THORNTON SWAYED BY GRUMETI STRENGTH
View from connections ahead of Friday's JCB Triumph Hurdle at Cheltenham.
It was the sheer "physical strength" of Grumeti that clinched his decision.
Thornton has won the Triumph twice on two Alan King-trained horses, Penzance in 2005 and Katchit two years later.
"There's not an awful lot between them on their homework and it's very difficult to split them," said Thornton.
"I schooled them both the other morning and I've gone for Grumeti just because of his physical strength and he's laid-back - not a lot is going to faze him.
"The other lad (Balder Succes) might just get a bit jazzed up by the whole occasion.
"Balder Succes could turn out to be the better horse, but at the minute I compare Grumeti to Penzance.
"He was very physically strong. He'll get bumped and it won't bother him. He's run on the Flat and is a hard horse from that."
King also believes there is nothing to choose between the pair.
"Grumeti has the Flat race speed and is pretty streetwise, whereas Balder Succes looks to have so much scope and is unbeaten in four races," the Barbury Castle trainer told www.alankingracing.co.uk.
"I expected Balder Succes to win his last race at Ascot but not with the contempt that he showed his rivals, and his hurdling was so slick.
This will be the quickest ground that he has encountered, but I see no reason why he won't act on it.
"We have always felt that good ground would suit Grumeti, so there are no worries there, and he has done nothing wrong so far and has shown that he is right up there with the best around.
"I just hope that both my horses get a clear run through the race, then we can find out which is the better of the pair."
Pearl Swan finished a short head in front of Grumeti at Cheltenham in January, only to lose the race in the stewards' room.
Trainer Paul Nicholls said: "Pearl Swan has improved enormously and he looks fab.
"He's not the sharpest in the world, like Zarkandar (last year's Triumph winner), but he stays and has a great chance."
Nicholls' other Triumph hope, Dodging Bullets, went down by one and half lengths to Grumeti on his hurdling debut at Kempton and accepts King's horse holds the aces.
He added: "Dodging Bullets is no forlorn outsider.
"He ran very green at Kempton and has improved, but he's going to have to improve to win a Triumph after one run.
"Grumeti looks the one to beat on form."
Tom George is bullish about the chances of Baby Mix, who bounced back from a poor run behind Grumeti and Pearl Swan in the Triumph Hurdle Trial on this course to beat Sadler's Risk in great style at Kempton last month.
"He made a really impressive debut at Cheltenham then he had a little bit of a blip. We got all that ironed out and he won well at Kempton last time out," said the Stroud trainer.
"He's fresh and well and we've kept him ticking over.
"He's looking good."
Sadler's Risk's regular jockey Richard Johnson believes Philip Hobbs' runner has improved since that race, and is optimistic he can reverse the form - especially granted a furious end-to-end gallop.
"I think he's definitely improved for his Kempton run and I'd be very hopeful I'd beat Baby Mix at Cheltenham. Any one of six could win - there doesn't look a lot between them," he said.
"A real true-run race will suit, but he had missed a bit of work before Kempton and will definitely have improved for the run.
"He seems in very good form."
