Listed in order of merit.

If you restrict your plays to the 1st and 2nd tiers with an occasional jump into the 3rd tier you will greatly enhance your chances of winning at Woodbine.
SB, I think there are many more you can add to your 3rd tier and your 4th tier can be moved to 3rd. Tier...JMO. I also think everyone you named can be bet without hesitation.
On trotters I love Trevor Ritchie, and Mario B.
