Are you planning on showing?
Judging by the video, he has natural gaits, but due to some rider error, his head is often behind the vertical, causing him to move in an up and down choppy manner, vs. long, low and smooth.
If he was ridden in a way that encouraged him to stretch down through is topline, instead of cranking his head back, he'd look really nice.
Once she let him have his head, especially at the lope, he smoothed out and looked like a pretty nice ride.
He's not super major WP caliber, but he looks like he could be a fun one to play around with at a local level.
That's what I want. Though will have to learn alot before I show. :) honestly they are asking quite a good price for him my friend looked him up on the AQHA site and apparently he has some 'points'.
