Paddy Power is not making a call between his mother Sabena's two runners in Saturday's Darley July Cup.
The bookmaking family will take both their Royal Ascot-winning sprinters to Newmarket at the weekend, with the younger Slade Power shorter in the market as he attained his first Group One win over six furlongs in the Diamond Jubilee Stakes.
Veteran Sole Power, who carries the first colours, is a five-furlong specialist and retained his King's Stand title last month.
Paddy Power said: "Slade Power is very straightforward and in great form.
"Presuming that he gets there safe and sound, that straightforwardness will help as you can put him anywhere in the race and he is adaptable and the great thing is he goes on any ground.
"Sole is a bit more tricky as the less rain there is, the better it is. But we're very lucky to be going there with two live chances and it's fingers crossed."
Asked which of the two he prefers, he said: "The ideal result is definitely a dead-heat!
"But the one-two either way around will do just fine and I will be doing all my usual reverse forecasts.
"I honestly don't know which to opt for - but one thing is for sure, I will be roaring 'Come on Power!' during the race."
John Gosden has warned Gregorian will only take his chance if the ground is soft.
The five-year-old has yet to run over the big-race distance of six furlongs and has done all his winning from seven furlongs to an extended mile.
His latest success came on the July Course in the Group Three Criterion Stakes over seven furlongs when heavy rain turned the going to soft.
"He's happy over a stiff six, he's happy over seven and that's probably his best trip," the Newmarket trainer told Racing UK.
"If we did get the ground we got for the Criterion then he would run. If we get normal summer ground, fast ground, he won't run and we'd wait. He's ground dependant.
"Gerald Mosse said last year not to be frightened of sprinting with his horse when he rode him in France.
"He's been a great old horse. He was unlucky in the French Guineas, he was knocked over in the French Derby. He's won his Group Twos and his Group Threes. If the heavens opened he would run."
