Brook says he will certainly know more after two or three runs over the 531 metre trip at the track.
“She is out of box seven on Monday, but I think the pace will be on early so as long as she's not too far off the lead I am happy with that draw," Brook said.
“Hopefully she can just cruise in behind the quicker starters, but finish over top of them.
“She will need a clear run through that first corner, but she shows good track sense. Also, in recent runs she's showing that her cruising speed is increasing with maturity.
“The two possible dangers are Allan Thrower’s, Alpha Humbug (box five) and Miss Slimm (box eight).”
Brook said his two derby runners – Kick Son (box two) and Just Like Mick (box seven) - were both strong chasers.
“Unfortunately, neither of these dogs are great box dogs,” Brook said.
“In fact Kick Son is one of the most unreliable box dogs I have ever had.
“We have done a fair bit of work on that recently and he has actually exited the boxes quite well in his last couple of starts.
