I've watched that video a few times and always enjoy it...I like her mane too...and I wish Assmussen would let Rachel's mane hang down...I just don't like the braided mane...especially on Rachel...she doesn't have a very pretty head, and her neck is a bit too thin (IMO)...so the mane hanging looks so much better on her...Zenyatta has a very pretty head & neck.
Anyway...for my taste...every mane should blow in the wind.
