You've shown us a couple of these videos before. What are you really looking for?
Some of these horses are at different levels of training ranging from not broke to very green to what seems to be well broke. Again, what are you really looking for?
If I had to pick out of this selection of horses, I would absolutely go with number 5. By far the best moving, prettiest looking horse in this group. He is very green, but with the right guidance, he'll make a heck of a WP horse.
Horse #1 would be my second pick. He's pretty going to the left, not so pretty going to the right. There are some issues that need to be addressed before I'd put him in the show ring. He needs to get more consistent with his head & neck. I would prefer to see him drop it just a tad. Then his right lead lope needs to be cleaned up. He gets a little sloppy - and this rider is letting him. It will take some time to help him build up the right kind of strength to improve his lope going in this direction. He does have a nice natural way of going & I like how they presented that in this video.
My third pick is horse #4, which we've seen before.
