Shinn reunites with Antino in the Group 1 Crown Makybe Diva Stakes (1600m) at Flemington on Saturday, having not ridden the gelding since last spring.
Jamie Kah had the ride on Antino when finishing a first-up fourth in the Group 1 Memsie Stakes (1400m) at Caulfield on August 31.
"Getting Blake back on I think is a positive," Gollan said.
"I've got no knock on Jamie, she's a terrific rider as well, but Blake sat on him so many times last spring, so he knows the horse really well.
"That's always a positive having a jockey that knows him that little bit better."
Antino was slow to begin in the Memsie Stakes, which dented the gelding's chances, and would like to see him begin better on Saturday.
He said he was loathe to do any barrier work with the gelding in between his Memsie and Makybe Diva starts.
"After this run and if we wanted to wait a month and play around with a few things, then we could do that," Gollan said.
"My plan was to run in these two races and then there is options and one of those is maybe do some different work with him and space him between runs, maybe a month, and go to something like the Toorak Handicap.
"We'll get through Saturday and see what the subtle changes do."
