My guess is that the sushi camp wiil not be looking to use a great deal of petrol early, and my second guess is they will not be looking to use tactics to derail those of others, in particular SU.
At his first run at this level, what sort of person would run the risk of burning a super horse like Sushi?? My tip is they look to put him in the race in the latter half and leave him a full head of steam win, lose or draw.
