While some would like to see the pair, who completely dominate the market for the final, kept apart until then to create suspense, that wouldn't be fair on their rivals.
So they clash in the second trotting heat at 10.02pm (NZ time) tonight, with Speeding Spur having a potentially big advantage drawing barrier five, while Tornado Valley starts from the outside of the front line at seven.
Both have gate speed, Tornado Valley's probably slightly higher after his steady diet of Australian racing, but co-trainer Dickie knows what he has to do to beat his key rival.
"Obviously I want to stay in front of him from the draw," admits Dickie. "I think I can because my horse has good gate speed and we couldn't have been happier with how he won on Saturday.
"He has been working really well, felt great in the race and I think his below-par effort in the Dominion [two starts ago] was just an off day. He has always loved it over here and seems happy to be back, so we're confident."
The Dickies, Josh and his father John, are getting to see plenty of Tornado Valley, as he is trained by Andy Gath, with whom Speeding Spur is stabled when he races in Victoria. "He [Tornado Valley] is a lovely horse and we are no good thing to beat him," says Dickie.
"So I suppose we are a bit like everybody else, keen to see how they match up against each other. But we have the advantage at the start and we will be doing our best to use it."
Every Inter Dominion needs a "wow" race to set up the rest of the carnival and the early battle of the trotting series favourites could be just that, even though it will be hardly definitive as a Grand Final guide, with that group one next week over 2760m and the final draw probably just as important.
After tonight's sprint heats, it looks likely all three New Zealanders in the pacing series would have won at least one heat with It's Pats Delight, who finished a brave second to Spankem on Saturday, drawn to get maximum points in his heat at 11pm.
His task was aided when one-time series favourite Shadow Sax, who was drawn in the same heat as I'm Pats Delight, was scratched tonight and for the remainder of the series after pulling up sore on Saturday.
Cruz Bromac is a hot favourite in the final heat tonight but his $1.45 fixed odds price seems awfully short considering his second line draw.
"It is never easy to win sprint races off the second line because you really need them to slow up in the middle stages to get into the race otherwise you have to come wide late," said trainer-driver Natalie Rasmussen.
So while he is vying for final favouritism, Cruz Bromac is too short to be betting big on tonight with luck such a factor.
Spankem races in the toughest heat of the night at 10.32pm (NZ time) and he would need to produce something special to win as he not only faces a second line draw but high-class opponents in Wrappers Delight, San Carlo and Tiger Tara.
Interdoms night two
• Second round of heats for the Inter Dominions are at Ballarat in Victoria tonight.
• There are three pacing heats and two for trotters, with New Zealand horses favourites in three of those.
• The clash between trotting final favourites Speeding Spur and Tornado Valley is the highlight of the night.
