I live on the west coast and have never seen a Roc baby on the west coast. I really don’t understand why and honestly don’t understand the apprehension with this stallion.
A few times I have talked to people (east coasters, west coasters don’t even know of him) they get really quiet and won’t really tell me what they don’t like about him.
Only thing I have heard is he didn’t compete for a long time.
I bred to him seeing his offspring and I can tell you he absolutely has improved my mares temperament and bravery. Not to mention he has numerous offspring competing in both the hunters and jumpers at big shows.
My 4 year old Roc is the bravest horse I have ever seen. He just jumped around a course he has never seen, only jumped once ever before and cantered over a water jump like it was a ground pole! Nothing phases him, and I can tell you his mother was the exact opposite. She is beautiful with jaw dropping movement and an amazing jump, but very spooky and hard to get quiet. This gelding is super quiet and looks at nothing. He was broke at 2 then was turned out to pasture as a 3 year old because I didnt have a lot of time or funds to keep him ridden. He started up again this summer and will show this fall, he learns very fast and retains all he learns which I love!
It just bugs me when people keep quiet when they could at least be honest with what their opinions are. I am always trying to learn about what stallions produce, good and bad and I hate when you only here one or the other. No stallion is perfect.
I am not trying to say Roc USA is the end all be all stallion, just that he passes on some great attributes that a lot of mares need!
Vent over. 
Oh, and my 4 year old Roc is my first homebred and consider it to be a successful cross and like to share my joy! I am not being coerced by a stallion owner to do so!
