The return to racing by Group One-winning stablemates Shoot Out and Rangirangdoo could be delayed with trainer Chris Waller to analyse their chances carrying big weights in Saturday's Tramway Handicap at Warwick Farm.

Shoot Out, the winner of the Chipping Norton Stakes in the autumn, has the maximum topweight of 62kg while veteran Rangirangdoo has half a kilo less.

Both are headed to the George Main Stakes on September 22 and Waller said of the pair, Rangirangdoo needed to get a run under his belt before the Group One.

"I'm disappointed because they will struggle to win," Waller said.

"I don't want them to have a gut buster first-up.

"I want to run Shoot Out but he has a good record fresh so maybe he could go straight to the George Main but Rangi needs to run.

"I'll have a good look at it over the next couple of days."

"It's hard if you can't get them ready for the early races in the carnival because they have to run in a race like this."

Waller's other entries, import Class Is Class and Said Com, have 57.5kg and 54kg respectively.

"I thought Class Is Class might have got a bit less," he said.

"He and Said Com will probably run."

Ten of the 18 nominations for the Tramway (1400m) are on the 54kg limit.
