Purely from a breeding perspective, I like  Mr. Hot Stuff.  Tiznow on top and Turkoman on the bottom.  FWIW, breedingwinners.com has Mr. Hot Stuff as the only horse able to get the distance.  And he did pick a Belmont winner a few years ago, a horse named Sarava.

Blind Switch: Seems to have an affinity for (Z)-7-[(1R,2R,3R,5S)-3,5-Dihydroxy-2-[1 E ,3
S )-3-hydroxy-5-phenyl-1-pentenyl]cyclopentyl]-5-N-ethylheptenamide (C25 H37
NO4). No long carbon chains at Big Sandy my friend!
