Premier Brisbane trainer Robert Heathcote has welcomed stable stars Buffering and Solzhenitsyn back to training to get ready for an assault on Group One races in Melbourne.

Both were given a few weeks off after running in the Stradbroke Handicap won by Linton on June 8 in which Buffering was second and Solzhenitsyn fifth.

Solzhenitsyn won the Toorak Handicap at Caulfield last spring but Buffering is still languishing as possibly the country's most deserving horse not to have won at the highest level.

The winner of more than $2.5 million prize money, Buffering has nine Group One minor placings to his name and Heathcote is determined to get a win on the board.

"They had their first morning back and they look in sensational order," Heathcote told Melbourne's RSN Sport Radio.

The A J Moir Stakes, which Buffering won in 2012, has been upgraded to Group One level this year and is again a target race along with the Manikato which has had a prize money boost to $1 million.

"In recent years we've gone down and he's won first-up at the Valley, the McEwen (Stakes) two years ago and then the Moir Stakes last year, and then we've gone onto Caulfield for the Schillaci," Heathcote said.

"I'm not so sure that the Schillaci will be on his agenda this year. Well see how he does after the Moir, but he's proved that he races really well fresh, so we may just target the Group Ones this year."

The Moir Stakes is on September 27 with the Manikato Stakes on October 25, the night before the Cox Plate.

Heathcote said Solzhenitsyn had not been over-taxed in the autumn and winter and he expected him to shine again.

"He didn't have a overly hard campaign through the winter, which culminated with an excellent run in the Stradbroke and I'm confident that, once again, we'll see Solzhenitsyn at his best in the spring," he said.

Heathcote said Fire Up Fifi would also be on his Melbourne team with the Group One Myer Classic her aim.
