"Not only is he only a one-win horse but he is very lightly raced and now he is straight into open class."
Frontman goes into his comeback race with only one trial under his belt and questions over what distance will prove his soft spot.
"We don't really know what type of horse he is going to develop into," admitted Forsman.
"He has the natural ability for these type of races but could also get Cups distances or even be a weight-for-age horse.
"He is a hard one to predict."
The stable also have Marroni, who has won four races and placed in an Easter Handicap, in the same 1400m and Forsman is hoping he has a short memory.
"The last time he came here [Te Rapa] he had a nasty fall so let's hope he has forgotten about that because he is a horse who has kept getting better his whole career."
Te Rapa being close to home should allow Forsman to get home in plenty of time to see Aegon, of whom he also shares in the ownership, take on some of Australia's best in the Makybe Diva.
Aegon earned his shot at the race with a luckless fourth in the Memsie last start and should be suited by the step up to 1600m, but meets some serious horses in Mo'unga, Tofane, Inspirational Girl, Cox Plate and Tancred winner Sir Dragonet, and Incentivise, who is favourite for the Caulfield and Melbourne Cups.
"Obviously it is a very good field but you have to expect that racing for A$1 million and he deserves his crack at it," said Forsman.
"He has a run under his belt and most importantly a good draw [barrier four] this week which hopefully will allow him to sit handy to the speed without having to do too much work.
"So he gets his chance to do something and we are really happy with how he has come on since the Memsie, but a lot of it might depend this week on what sort of run he gets."
Aegon is also on a rare two-week back-up after usually having his races more spaced but that could be negated by the fact he didn't have a hard run in the Memsie.
He is booked to return to Cambridge next Wednesday but if he was to excel on Saturday he could stay in Australia to prepare for his main aim of this campaign, the A$7.5m Golden Eagle at Rosehill on October 30.
