With plenty of speed drawn inside the pair, either could win but equally they could both get beaten and go good races.
Dickie is on the likely favourite Sertorius in race four and the big horse looks headed to open class but his stablemate C K Spur is rated at least as good a chance tonight.
"It is 2200m and Sertorius can be a bit slow away, which would be a real disadvantage in this grade with some experienced older trotters drawn behind him.
"I think Sertorius is an open class horse in the making but if he is slow and C K Spur pings the tapes then he could beat him. So it is a tricky one."
The same applies in race six where Sex On Fire is having only her second start after beating older horses as a juvenile by eight lengths.
"She obviously has the ability but she has taken a while to come up this time and our other filly (Star Of Olesya) is race fit and also won easily last start.
"So while there will be plenty of people keen on Sex On Fire, if you add in a handy filly like Aoraki it is another race I could easily get beaten in.
"So I'm hoping to have a good night but if I went away with two wins or none I wouldn't be totally surprised," Dickie mused.
Another man set to star tonight is Steve Telfer, who sits third on the national trainers premiership and has two huge hopes in American Brave (race seven) and Parker (race five) with a pretty strong support cast too.
Barry Purdon looks the dominant trainer in the two-year-old race, with Star Of Montana and Supreme Dominator both looking youngsters with good seasons ahead of them.
Friday fancies
• Best: American Brave (R7, No.5): Only three but headed for open class.
• Suited: Bettor Step Aside (R1, No.7): Better than this grade and small field should help with draw.
• Odds: Djokovic (R4, No.5): Drops out of group racing and loves a hard-run 2200m.
