Cook was a harness driver early in his career but quit the sport when he was 26.
“I had been involved with trotters since I was 14 but I gave them away when they shut down harness racing here when I was 26,” he said.
Cook had also accepted with Rock 'N' Sol in the Open Handicap but has elected to run in the Benchmark 55 Handicap.
Rock 'N' Sol is also an eight-year-old and is coming off a last start sixth to Freckle Rock in a 1560 metre Benchmark race at Mackay on September 19.
“I think Rock 'N' Sol is going well and will be hard to beat on his recent runs but I think Brad had a slight edge on him if he started in the Open,” Cook said.
“Brad will go out for a break after this run and come back for another go at the Country Cup on Magic Millions day at the Gold Coast in January.
“He finished midfield in the Country Cup this year but it rained that day and he’s legless in the wet."
