I use Sire Ratings in order to see how well the Sire/Damsire/Broodmare Sire does for FTS but also for on Turf, Synthetic, and Off Track plus seeing if the pedigree shows any specialists on Turf Sprints/Routes or Stamina Index "1"'s
In the walking ring here is what to look for a good 2yo:
Little sweat: A lot of it= toss!
The horse has bounce in step and is playful with caretaker
Nice "car-like" shine to his/her coat
Ears up with being alert to all surroundings with head held high
If the horse's tail or mane is braided= connections have high hopes for it today!
Legs are looking sharp and clean; Watch and see how the horse behaves with stepping around
Has good muscle especially in the legs neck and butt area(s) but not too much
Not overly fat anywhere and is fit (looking for smaller well bred horses)
The horse warms up well with the outrider and does not act up at any point of a warm-up
The horse shows no aggression or anger to anything; Is calm cool and collected
I probably missed a few things above but that is what I can think of right now
Another thing to note is seeing how much the horse went at auction because if the Sire has a big stud fee and the horse is sold for less; there is definitely something wrong that drove down the price of this horse
Also, look at the workouts I like to see evenly spaced out workouts for horses prepping for their first race and like to see sharp times too which helps their chances today!
If a trainer has 2 entered (uncoupled) always take the higher-priced horse as this will put you at a bigger price vs the shorter price that everyone else is on plus this horse wins more often than not!
Hope this helps sorry lots of info
