So too is Lazarus (barrier six) but Purdon has Smolda (one) and Our Waikiki Beach (three) drawn to be handy.
"A lot of made of the barrier draws but the history doesn't bother me," says Aiken.
"Hector's draw doesn't look great but he still has the best gate speed in the race and if we go forward on him he will come back to Josh [driver] when he needs to.
"But he is also just as good coming from behind. That is how he won the Len Smith Mile here last season."
But Aiken says Lennytheshark having the slightly better barrier draw does make him at least as good a chance as his stablemate.
"He is flying and we know he went 1:47.6 last season running second last season so he won't need to go much faster.
"So we are not losing sleep over the draws or what the history books say because there are three great horses drawn wide this week and maybe they will end up carting each other into the race."
Lazarus remains the favourite around Australasia, between $2.40 and $2.60 depending on where you bet, but there are huge discrepancies in the prices for other runners.
One major Australian bookie has Hectorjayjay at $3.80, another at $5.50.
New Zealand-trained pacers are favourites for the Mile, the NSW Oaks (Partyon), NSW Derby (Vincent), Ladyship Mile (Dream About Me) and Bohemia Crystal Free-For-All (Chase The Dream).
