Best sprinters at half way point ??

it s halfway till the BCS, and i think, (seriously) the best sprinters are,, in order.

1)Songster (every race is a new record of some type)
2)Foggy
3)Silver Train
4)Too much bling (if ridden off the rail path, Gomez ??)
5)Keyed Entry

i don't know where commentator would fit, as he hasn't run this year
