Great lists and I'd agree with so many of your choices but two things...
First off poor Veyron! Can't catch a break.
Hopefully next year...
Second for Horse of the Year - and you know how much I love Mufhasa, Jimmy et al - I think Shez Sinsational wins it.
Of course I'll be thrilled for whichever horse wins as they're all just soooo damned good!
Exciting stuff!
