Mike De Kock believes Newmarket's July Course will suit J J The Jet Plane better than Ascot in the Darley July Cup.
South Africa's champion sprinter won his first start in England, but upped in class for the Golden Jubilee at the Royal meeting, he could finish only fourth.
"I think this track will suit him a lot better than Ascot and tactically I think the race will be more up his street as we can sit off the pace with him rather than let him run on," said De Kock.
"He did finish his race well at Ascot. He battled back past a few horses who passed him and he never gave up. That race will have really put an edge on him and he is 100 per cent.
"The Aussie horse, Scenic Blast, is going to be very tough to beat, but we'll be out there trying hard, I can tell you that much. It's a hell of a race with Paco Boy in there too and I'm really looking forward to it."
In fact the participation of Queen Anne winner Paco Boy and fourth home Main Aim is in some doubt if the ground continues to dry out.
"If the ground is suitable, we will run," said Paco Boy's trainer Richard Hannon. "But Newmarket can dry up quickly and if we feel the turf has dried out too much, we won't hesitate to pull him out.
"We don't think we saw anything from the Golden Jubilee at Royal Ascot to worry us too much and while Scenic Blast is obviously exceptional, we are not worried about the opposition, just the state of the ground."
Main Aim's trainer Sir Michael Stoute said: "We're going to walk the track in the morning and make a decision. We'd like the rain to make the ground easy."
