Andrew Lynch admits Flemenstar's aims later in the season will become clearer after tomorrow's John Durkan Memorial Chase at Punchestown.
Lynch has struck up a great partnership with Peter Casey's wonderful seven-year-old, who has won his last six races including two at the highest level.
Only four go to post in the Grade One but all have won races at that level and Lynch is taking nothing for granted, particularly as Sir Des Champs is another prominent in the ante-post betting for the Gold Cup.
"There's only four in it, but it's a competitive race," Lynch told At The Races.
"He won well over two and a half (miles) last year at Fairyhouse, albeit in different ground, so it's a stepping stone to three miles and we'll see how he gets on on Sunday.
"Touch wood he jumps and he travels, and all being well he'll step up to three miles at Christmas.
"Sir Des Champs is a very good horse, he's unbeaten so it will be competitive but hopefully my lad might do the business - we'll know an awful lot more on Sunday."
Rubi Light won last year's race for Robbie Hennessy with Lynch on his back but Barry Geraghty takes over this time.
While Hennessy acknowledges it is not ideal making his seasonal return in such a hot race, his options were limited.
"We had no option but to start him off here really," said Hennessy.
"He got a knock early on, otherwise he would have gone to Gowran but it just set him back a bit.
"He won this last year and is two out of two at the track.
"It's a hot race but with a horse like him there are no easy options.
"Two and a half miles in soft ground seems his optimum, he ticks all the boxes.
"Barry Geraghty has won on him and knows him well. The others are stepping out of novices and if they slip up we'll be there to take advantage.
"He's as fit as we can get him at home, he's had a couple of schooling races so we'll see how we get on."
