No experience with Qredit, but I have a Contucci baby and she is wicked smart, very affectionate and people-oriented, and very trainable. She’s also a great mover - lots of talent to both push and sit. I’m an amature and have been having a blast with her. Currently getting scores in the 70s at second level, and she’s showing lots of talent to go farther.
That said, she won’t put up with bullying or a tactless rider, but that seems to be pretty common with mares, so I don’t know that I would ascribe that uniquely to her sire (and I’ve heard her dam sire could be a bit firery, so could be from there, too).
