Caduceus, who galloped with Volkstok'n'barrell, is no slouch, but measured against his companion it would be a schoolboy playing halfback for the All Blacks at the weekend.
"That will tighten him up, but it's a matter of how much," says Logan.
"I can't afford to run him first-up on a track too testing, whether it's the Makfi at Hastings or Melbourne's Memsie Stakes.
"It could be that he has to have a float trip to a few race meetings to tighten him up physically, we'll see."
No jockey has been decided on for the Victoria campaign, although Craig Williams was given first option.
Williams rode Volkstok'n'barrell to victory in the A$500,000 Rosehill Guineas and into third in the A$2.2 million Australian Derby, but told Logan he will be riding in Japan on the weekend of the Memsie Stakes.
"So we're about to contact Hugh Bowman and Damien Oliver to see if they're available."
The stable is delighted with the progress of boom rising star Hassellhoof, who will race next at Ruakaka on the 29th.
History tells us there are a couple of hundred ways you can lose a race.
In-form apprentice Brendan Hutton potentially found a new one at Te Aroha on Sunday - sun strike.
Hutton won the final race on the card on Bee Tee Junior, but not before being blinded by the sun.
"Coming down the home straight, the sun was being reflected towards us off the mirror strip on the winning post. I don't know how much the horse could see, probably not much because I couldn't see anything."
Fortunately, Bee Tee Junior was lengths clear when the problem occurred in the closing stages and won, despite running erratically through the lack of vision.
Trainer Shaune Ritchie has something of an opinion of Bee Tee Junior.
"He'll stay and I'm trying to get him up to a middle distance to get him ahead of other stamina horses, most of whom are being held back waiting for decent tracks."
