What distance have they been working over Flame?
Aegean was able to run through JA at Churchill Downs and was going further away at the end. Doubtless JA would have set a blsietering pace which Aegean was able to take a lead from and use her stamina. I've read a report that Aegean beat her in a public gallop on turf in the states (narrowly) when Wes Ward was working out who he would be bringing over. Aegean wouldn't be the first horse whose shown a preference for the racecourse ahead of the gallops. The question is have they been working at full racing speed over 6F's? Otherwise surely they've been working on JA's terms. So far as I can gather Ward normally lets them have a burst at full speed over 3F's and it's probably not too surprising that Aegean hasn't necessarily lived with JA (on Wednesday nothing did)
Acclimatising would be my only worry. I'm not even bothered about the draw. Strike The Tiger and Scenic Blast both came from a high berth. If the horse is good enough, it should be able to defy any bias.
I didn't back Yogaroo incidentally. The same crudes methods I'd used to find Strike The Tiger and convince myself that Jealous Again couldn't be beaten, also led me to the conclusion that Yogaroo could and was by far and a way the most vulnerable of the American 2yo's
