"I don't base who I am driving on who is the best chance, often it can come down to an array of other reasons," explains Purdon.
"The filly I am driving — Paramount Princess — goes really well and so too does Mexicana, even though she can be a bit tricky on the bends while she is still learning.
"But Wanna Play With Me is trotting well and is our top chance," he told the Herald yesterday.
The stable also has four juvenile pacers in race four and Bettor Call Me (No1) has the draw and the experience to be the best chance.
"They all go well but for these young horses the draws can be crucial. He [Bettor Call Me] ran second last campaign in a Sires' Stakes heat and I think he will have gate speed to use the draw.
"Of the others, Stag Party and Bettor Twist are both on debut and should improve whereas I think Delightful Dude will need one run, maybe two to see his best."
Italian Lad (R5, No15) would seem to have a decent class edge on his rivals and should win but has at least two factors against him.
"He comes out of those good three-year-old races which were all mobile so reverting to a stand we have put him on the unruly," says Purdon.
Aqua Sancta (R9, No1) has burned the punters before but Purdon says he has strengthened this campaign and from the ace might be too good.
● The stable roll out their big guns such as Auckland Cup winner Self Assured, Princess Tiffany and Another Masterpiece for their first race starts of their new campaigns at Addington next week while they also have 10 horses booked on a transporter next week bound for Auckland where they will add huge depth to the northern racing.
The team will be headlined by Inter Dominion trotting champion Winterfell who prefers right-handed racing and Purdon and partner Natalie Rasmussen will treat the horses on a case-by-case basis as to who returns to Canterbury for feature races, who stays in Auckland and who heads to Australia.
