With Golden Slipper favourite Sepoy still on target for Saturday week's $3.5 million showpiece, just who joins him from the Peter Snowden stable will become clearer in the next 48 hours.

Snowden will send Helmet to the Randwick barrier trials on Friday before making a decision on whether he takes his place in the world's richest race for two-year-olds.

Darley's head trainer also has three fillies in Saturday's Group Two Magic Night Stakes (1200m) at Rosehill, the final qualifying race for the Slipper.

"Helmet is trialling on Friday and we'll make a decision after that as to whether we run in the Slipper or the Schweppervescence next Saturday," Snowden said.

The Group Three Schweppervescence, registered as the TL Baillieu Handicap, is over 1400 metres and was won by stablemate Skilled last year on his way to a second in the Sires' Produce Stakes and victory in the Champagne Stakes.

Helmet has won two from two this preparation at Rosehill and was set to contest the Sires' Produce Stakes (1400m) in Melbourne on March 12 but was scratched at the barrier.

In the Magic Night Stakes, Snowden has Aerobatics, Disputes and Altar taking their places.

"Aerobatics has drawn a terrible barrier (12) but she is probably the pick of the three," Snowden said.

"Disputes has had two trials and is going very well, and Altar only had the one run at Flemington but ran very well for third last Saturday week (in the Group Three Breeders Stakes)."

The winner of the Magic Night Stakes gains automatic entry into the Golden Slipper.

Dominant Blue Diamond winner Sepoy lost his vice-like grip on the Slipper when he was beaten by Smart Missile in last Saturday's Todman Stakes on a rain-affected track, but the colt remains the $2.90 favourite.

"He is fine and I just hope the weather stays with us and we get a good track next week," Snowden said.

The premiership-winning trainer said Sepoy's effort to battle on for second on ground he wasn't handling was what he was able to take out of the colt's defeat on Saturday.

"With the preparation he had, if he had gone off and got beat eight lengths then that would be the horse telling you he had had enough and he had no more chase in him," Snowden said.

"But the fact he just kept coming and coming and coming will tell anyone the horse is still on a high, he hasn't gone backwards at all and he looks very good in himself."
