Blitzing Mayhem, who won at group one level on this track in May, pinged away smartly from trap seven and he was never headed after when delivering his 30.16s heat win. He must adopt those same lid pinging tactics from the eight trap here.
Lady Shambi showed her strength in taking out her heat in 30.29s.
Her known strength at the business end will turn into an asset if this race turns into a torrid finish. She is in trap six.
"All three of my runners have pleased me during the week and they are all set to deliver bold races on Friday. I'm more than happy with them," said Clark.
Huntly trainer Denis Schofield qualified two runners with Sassy Road getting up late to win the other heat in 30.12s.
She has been rewarded by being provided with the desired one trap draw here.
Jannik is also a previous group one winner on this track and he returns after his stout finishing five-length heat, second to Lady Shambi.
"I'm rapt with Sassy Road's draw and that has strengthened her claims," said Schofield.
Jannik will be an improved dog for Friday as he missed work going into his heat."
The sole South Island qualifier comes from the Canterbury-based Ray Adcock kennels.
Robbie was bold in delivering his 2 length heat, second to Blitzing Mayhem, and he has drawn nicely in trap two.
"I believe he will give his supporters a great run for their money. Robbie is ready for a big race on Friday," said Adcock.
The remaining two finalists are provided from the potent Lisa Ahern kennels.
Always Welcome was gallant when trying to lead all the way before he was gunned down late by a head by Sassy Road.
Tifino led the chasing pack home behind his litter sister Night Pearl when delivering his five-length heat second to her.
