The most experienced runner and the highest earner in Saturday's Group Two Silver Slipper, Mishani Honcho is also among the least fancied.

The Brisbane two-year-old is in Sydney to convince connections to pay a $150,000 late entry to run in the $3.5 million Golden Slipper next month.

He will be given two chances to justify the expense, starting with Saturday's Group Two race at Rosehill where he meets several of the Golden Slipper market leaders.

The winner of four of his seven starts and more than $330,000 in Queensland, Mishani Honcho is in a field which includes one of Godolphin's leading chances, Ottoman.

Ottoman is the TAB's $2.60 Silver Slipper favourite ahead of the Peter and Paul Snowden-trained Paceman at $3.80.

Mishani Honcho is at $35 and Ross admits it is a daunting task but one he believes the gelding can handle.

"At the start of the season I rated my filly Frequendly my best two-year-old but this bloke has overtaken her. In fact I reckon he is the best horse I have ever had," Ross said.

"Even if he is beaten we will stay on and race in the Todman Stakes at Rosehill a fortnight later. He would have to race well in the Todman for us to press on for a Golden Slipper start," Ross said.

"We didn't nominate him for the Slipper but if he races well in the Todman we will pay the late-entry fee. We have entered him for the ATC Sires' during The Championships and that is our back-up race," Ross said.

Ross has been an occasional visitor to Sydney for many years but is yet to lead in a winner.

"I first went to Sydney with a horse called Car Club many years ago when I was training at Cunnamulla (in western Queensland)," Ross said.

"I have been back a few times, most recently in 2013 when I took three horses down and got a couple of minor placings."

Mishani Honcho ran third as odds-on favourite at his most recent start at Doomben but on reflection, Ross said the gelding was not suited by the early slow pace.

"I was initially disappointed by the Doomben run but when I looked at the sectional times it made sense," he said.

"They walked early and then got home the last 600 metres in about 33-1/2 seconds which meant he had to run record time to win from back in the field."
