Both are likely to be nominated for the Auckland Cup but it looks a more likely target for Hughie Green, as The Orange Agent can be set for the group one Queen Of Hearts on December 18 and also has a raft of four-year-old options her year-older stablemate does not.
"To be honest, if I had to choose between the pair right now I wouldn't know which way I would go," says McKendry.
"They are very different horses and maybe from an Auckland Cup point of view Hughie Green would be better suited because he has the standing start experience. I don't think the mare will head that way at this stage, which will suit me fine."
McKendry may have left his native Methven decades ago but he has always retained his southern understatement, although cracks in that armour appear when he discusses his current pair of superstar driving engagements.
"They both have real speed and stamina, which gives them that high cruising speed.
"Sometimes when you are driving Hughie it is like you are a passenger sitting on a train watching him cruise past very good horses, he just does it that easy.
"It is quite freakish.
"So to have the two of them to drive at the same time is a nice feeling."
The entries for the Auckland Cup close on Friday so TAB bookies should open their first market next week, with Have Faith In Me likely to be the favourite ahead of the likes of Sky Major, Tiger Tara, Hughie Green and Mossdale Conner, with The Orange Agent likely to be longer because of the uncertainty over her Cup plans.
But while McKendry has plenty of respect for Have Faith In Me, he also has a warning for those backing him and his wayward standing start manners in the Cup.
"Hughie feels really safe from a stand and Have Faith In Me couldn't give him a five-length start and beat him," he says matter-of-factly.
Meanwhile, driver Zac Butcher has escaped suspension for Sky Major flattening the tyre of Mossdale Conner in the New Zealand Free-For-All, instead being fined $800.
