Alright I do understand what you're saying.
Unfortunately I cannot afford those horses, but they are very beautiful.
I would critique these horse differently depending what sort of rider you are. If you can train a horse to 3'6" you can take on a pretty big project. If you are able to ride a made horse over a course, that would change things up a lot. If you can ride a hotter horse, that too would open more options. Also, you said 3'6" prospect. Are we talking local or bigger shows? It's not impossible to find an A prospect on a budget, but your ability to bring a project along will make a difference in how much horse you can get.
I think the gray is cute and he looks easy to ride and very smooth. His jump style is alright. However, I think he lacks the athleticism to be a 3'6" horse nor do I think he'd stay sound long term with those posty hind legs. He's very drafty, travels on his forehand. I did see him blow out though the shoulder a few times and the rider had a hard time getting him around the corner. His new rider will have to be a strong rider to get that corrected. I mean strong both in the sense of a good rider and also physically.
The Dutch cross. This has apparently been in training with a pro, who I assume is not the rider in these videos. I see a horse that is pretty willing to pack around someone who bobbles, hangs, and is clumsy with the aids. I would sit on him to figure how how much is habit and how much is because of the rider. He has the athleticism you are looking for. Whether he can do a nice hunter jump, hard to tell, but I think he's worth a look. Oh, he's going to need a chiro at the very least, but I would do a very thorough PPE if all went well.
The TB. I love TB's and I think if you are on a budget, this is the way to go. This competent rider is making this horse look easy and quiet, but this horse is very goey. Not a problem if you can ride a goey horse, but you need to be honest with yourself if you would enjoy that kind of ride or not. Horse looks super green over jumps in the pic, so no way to comment on form. If the ad description is correct, the pic and vid is old. He looks fairly athletic as are most TB's.
I believe with the help of my trainer, I could train a horse to 3'6. Easy? No, but I believe in myself that I could do it.
I'm starting to understand what your saying about the gray, I'm bummed but that's just how it works I guess.
So you think the Dutch I should look at? I wasn't sure with at that price, he comes off like he has lots of re training to do, but I could be wrong.
I love TB's as well, I went to look at a wonderful one but unfortunately with pricing it just didnt work out. I don't mind goey horses, I want more of a change.
Jeeze, you need to look at horses for me!
Thank you very much.
