Two horses at different ends of the spectrum will tackle a rich race at Moonee Valley for trainer Henry Dwyer.

Tokyo Tycoon is coming off an injury break while Rocky Boomboa is race-fit as they head to Saturday's $150,000 race restricted to VOBIS Gold nominated horses.

A debut winner at Ballarat in May, Tokyo Tycoon underwent knee surgery and required three months in the paddock.

"A lot of the time you are a bit apprehensive about the outcome," Dwyer said.

"With modern technology the surgery was pretty good and he's one of the ones that has come through it well."

Dwyer holds a high opinion of Tokyo Tycoon and says the colt does things on the track that only good horses do.

But the trainer said the three-year-old is likely to benefit from the outing.

"In the back of my mind is the knee surgery so I haven't hammered him on the track but he's had sufficient work to be ready to resume," Dwyer said.

While Tokyo Tycoon has the potential, stablemate Rocky Boomboa doesn't possess the same natural ability but makes up for it with a professional attitude.

Rocky Boomboa scored his maiden win at Ararat in November before running sixth over 955m at Moonee Valley on December 18.

"He always begins like a bullet and will put himself there somewhere," Dwyer said.

Dwyer also runs Boomwaa in the William Hill Handicap after deciding to bypass Friday's Group Three Standish Handicap.

The gelding has been out of the winners' circle for more than 12 months with his last win over Saturday's course and distance.

Previously trained by Robbie Laing, Boomwaa will be having his third start for Dwyer, his latest a sixth behind Durendal at Flemington on December 12.

"While he runs good races he struggles to win just because of his racing style," Dwyer said.

"We've tried to address that a little by trying to get some cover at his last couple of runs."

Dwyer says Boomwaa is becoming more adaptable but he will leave it up to apprentice Michael Dee as to where he will be positioned in the run.
