"We have been restricting him to 1600m, just to get his race pattern right and to make sure that he is spot on before we get to 2000m," he said.
"If he was just a miler it restricts us in how much we can win, but if they can get up over ground the sky is the limit for a horse like him, with the pedigree he has."
Ritchie also has Swords Drawn nominated for the group three SkyCity City Of Auckland Cup (2400m) at Ellerslie on New Year's Day and said the weights will determine which race his charge will contest.
"We have put him in everywhere just to keep our options open, but that will be his sixth run in, the Dunstan Final, so you would think that is the right race for him to peak in and then perhaps have a little breather and reassess in autumn," Ritchie said.
"We have him nominated for the City of Auckland Cup just in case he gets up in the weights in the Dunstan Final as well.
"I think we learned a lesson from a horse like Prince Jabeel last season when he won the City of Auckland Cup down in the grades.
"He automatically went to the top weight in the Wellington Cup [group three 3200m]. That's a concern for me, I don't want him to charge up the handicaps too quickly because he has only just come out of 65 grade and I don't think he can carry weight as well.
"I think the 60 kilos last time was probably why he was beaten."
Swords Drawn will likely have one more run in preparation for his New Year's Day assignment.
"There is a [rating] 72 race next week at Ellerslie, which will be two weeks after his Pukekohe win, and that should set him up nicely into the Dunstan Final and that's the one I would really love to win with him," Ritchie said.
