I seem to see him on the dam’s side a lot in the sport horse types I like. My new OTTB’s grand-dam is by Quiet American. He hasn’t evented yet (and may not, not sure which direction he will go yet) but he is a lovely type. By Congrats and I think that the AP Indy/Fappiano cross is a nice one (although calling it a cross might be a bit of a stretch, so far back).
Palm Crescent is the only one directly by him I can think of at the upper levels but I am sure he shows up more often further back in lots more. You get Fappiano and a double of Dr Fager with him which I think is great for jump and athleticism. I think there have been a few threads on him a while back, so you might find more with a search!
