"You would have to say that Smoken Up is the horse that we are most fearful of," Garry Hall snr said of the Menangle Park specialist, who boasts five wins from eight starts at the circuit.
Im Themightyquinn has met Smoken Up on four occasions and finished in front of him three times.
Their latest encounter was in the Interdominion Final in New Zealand, when Smoken Up crossed the line in front but lost the race after a positive swab. Hall feels Im Themightyquinn is now more lethal and is banking on the race to be run at a solid tempo that will allow his powerful pacer to finish over the top of his rivals.
"He is in good form, I can't fault him, he is going better than he was in the Inter Dominion series so he is probably worth a shot and that is why we are coming," he told the Herald Sun.
"Even though the horse has come back better than ever, the Miracle Mile is the least suitable race for him on the Grand Circuit. There is no doubt he is a better horse in longer races."
Dubbo pacer Karloo Mick clinched the final spot and trainer Barry Lew has indicated his 11-year-old will be in top shape after finishing well down the track behind Mr Feelgood.
