I liked Passing Shot in the Breeders' Stakes until I saw he got such a wide gate! I definitely think the Roger James pair of Tavy and Shees Flawless are good chances.
There isn't much on Anzac Day, surprisingly. There's a minor stakes race at Awapuni, but that's about it.
No, I haven't heard anything about Giant Turtle at all, sorry! I will keep a look out. If I have a spare moment in the next few days I might try calling someone in the stable.
