Danny Williams is a big supporter of the Highway Handicaps for country-trained horses but has so far only had a half-hearted celebration.

The Williams-trained Shutter Bug could not be separated form Pera Pera at Randwick on Saturday and the Goulburn horseman is determined to get an outright win.

He has entered Istanbul and Kopi Luwak for the next edition at Rosehill on Saturday over 1200 metres.

"I think I've had runners in all of them since the series started," Williams said.

"I thought we had won with Shutter Bug and it would be nice to get a win on our own."

Istanbul, who will be ridden by Tommy Berry, was unplaced on his return from a spell at Goulburn and Williams admits he was disappointed.

"I expected him to run top-three so it was a bit disappointing but he has done well and I expect him to improve," he said.

"I'm not sure what to do with Kopi Luwak. I don't know if I want to ask him to carry 57 kilograms so I won't make a decision until later in the week.

"He's still a maiden and there's a race at Randwick on New Year's Day that might suit him better."

Kopi Luwak has had just one start for a second at Canterbury to Barood who is being touted by the Snowden stable as a potential Group One performer.

The three-year-old holds a special place in the stable, not just because of his talent.

"He is the horse that broke my pelvis," Williams said.

"He bucked and I tried to stay on but he kept bucking and eventually I came off and he ran off.

"I figure a horse with that much character must be able to gallop and he can."

Both Istanbul and Kopi Luwak are owned by June Baker who is a major factor in the latest chapter of the Williams story.

After a stint running Tony McEvoy's Hawkesbury stable, Williams returned home to his family in Goulburn to start again.

"June is a fantastic owner. I only had four horses at the time and she offered me three and then another three and 12 months on the stable has grown," Williams said.
