So I have been looking for a larger horse to show in the hunter circuit as I have a top of the line large pony who I love dearly but I'm 5'8" and look ridiculously huge on her haha. I show her at the smaller events but I am looking for something larger as well that I can take up the levels a bit more. So my trainer has a 6 year old 16.3-17.0 warmblood gelding that I like very much but he is just coming off of stall rest and I'm not sure of his potential. As a 4 year old in his first season of riding he came up unsound and he was x-rayed and ultrasounded and the only issue found on either was stretched ligaments. The vet believes is was because in his 4 year old year he had an enormous growth spurt (went from about 15.2 to 16.3) and grew too quickly for his body to keep up. He was then on stall rest for a while and once cleared for turnout again went outside and pulled a shoe irritating the collateral ligament thus putting him on stall rest again. He is now back under saddle lightly at the walk and trot 3x per week for now to slowly build his muscling and strength back up and also now has special shoes to release pressure off the tendon and ligaments of his legs which he may not even need for very long. The vet believes he will not have any restrictions once he is brought back slowly. I'm not experienced enough to really know how to be able to determine anything myself on this matter.
I would be looking for a horse to show up to 3' hunters maximum possibly jumping 1-2 times per week at most as I don't like jumping much more than that. I'm not looking for hack winning movement or anything as I am more in to showing in the over fences classes myself. I've been told that he has a very correct jumping form but I've never seen it myself. In the video it is my first time riding him and he had been in for a day and has only been ridden a few times since cleared for physical activity so he wanted to move out but I didn't want to do more than he should at this stage in bringing him back.
What I'd like to know is if anyone has experience with this sort of previous injury and what it might look like for him in the future. If anyone detects lameness in his gaits (I didn't feel any, but multiple eyes can't hurt). And how his conformation/movement would help/hinder me in the hunter ring. Thanks so much!
