If you'd indulge me, I would like to have a bash at this. Long time since I've done weight ratings (my spreadsheet still returns old-fashioned odds), but here they are:

3. Ruben 11/4
6. Hardy Steele 11/4
5. Pink Fit 13/2
7. Call Me Syd 8/1
2. Under the Bridge 10/1

My current method (consistency, fitness, class, form) has Ruben $3.80, Hardy Steele $5.50, Cauvery $7.20, Under the Bridge $7.30 and Pray in Vain $7.90.

The way I've been going, this should give people a guide on the ones to avoid!
