Highvol won again shortly after before going out for a break, but after his first run back as a three-year-old, Ryan altered his thoughts and was instead considering the Derby.
"He ran so well in the Stutt Stakes at Moonee Valley with the blinkers on and he beat home Vinrock that night, we elected to go to the Guineas," Ryan said.
"He and (Derby favourite) Observer are the only two horses out of the Guineas running here.
He drew wide in the Guineas, and he was back and it was an insignificant run, but then he did a good job in the Geelong Classic going from the mile to the 2200 metres
"I'm surprised how well he came through it, and he's come on from it and can improve again."
Ryan concedes Highvol's pedigree, being by Microphone from a Hussonet mare, may count against him over the extended trip whereas Miewa has the pedigree to run the Derby distance, being a son of Maurice who sired 2021 winner Hitotsu.
"They're both very well," Ryan said.
"They're both good in the feed bin, their bloods are good, really a mirror image of each other.
"All I can say is Meiwa is the class horse with the pedigree, but Highvol wouldn't shock me either."
