Ok small insight - the mare's damsire is by Misty Flight. I own a horse by a different son of Misty Flight, Dancing Flight. I bought my horse as a 9yr old stallion off Garden State Racetrack to be my long format super star LOL. He had some ridability issues I didn't know how to address back then, so he competed through Prelim, and later did the A/O hunters with me.
He was a fantastic mover with tons of suspension, and a great, back cracking scopey jump. He has great feet, and has been sound, sound, sound
I love the Princequillo lines. The two horses I have had with him up close (I had one 25 yrs ago that was line bred to him) have been very sound, durable athletic horses.
Also, a few years ago I had an In Reality line filly, by Judge Smells. She was a nice little thing, a hunter type, nice jump to her, but very spicy.
