I think she's a beauty ;)
Apart from her lack of muscle, which will come with age as she's only 4, one of the best looking TB's i've critiqued so far on the forum. Most of them (not all) are high in the withers or else sickle-hocked to some degree.
Her pasterns are a bit long, but I don't believe that will have much effect on her overall performance.
I'm not a jumping expert so i'll leave to for others to judge, but she looks to be doing quite well in the photos! She certainly jumps high!
Based on her style of jumping, I would say she would probably excel more in jumpers. She really uses her body for a nice round jump. While her knees are up they aren't perfectly even and tightly tucked, like what they look for in the hunter ring.
She is a very nice horse and I wish you good luck with her!
She uses her neck well. She could tuck her knees in more but she will learn the over time. I think she would be really good for jumpers. She does have good movement for hunters. But she looks like she has the power and speed to win in the jumpers. Either way I think she will do well
Being a hunter myself, I see a very nice horse with tons of potential for both hunters and jumpers. She does have a very round, scopey jump but not the kind that would pin her high in the hunters...yet. With training she may be an amazing hunter, but as of right now I see a jumper. She uses her back end really well and with time and more gymnastic work her front end will even out too, which could make her a nice hunter, but more likely a nice jumper. She gives plently of room between the jump and herself which means that there is a very slim chance she will be knocking any fences. :)
And honestly, the best hunter horses aren't "laid back and slow". Hunters need to demonstate huge scope (which is why with training yours may very well be a successful hunter) and a very forward canter in order to make all the striding. My horse is definitely not the most laid back horse out there and he has a very spirited canter, yet he champions every time. It all depends on what your horse likes and you like, and I'm sure you'll do well if you both enjoy it. :)
Who says she can't do both?
My boy is super slow and laid back, but manages to excel in both the hunters and the jumpers. When we get more training in him he'll hopefully by doing the A/O hunters, 1.10 m jumpers, and 3'3" equitation by the summer.
And blush, I don't know if I agree with you. The best hunters I've seen are slow and laid back with a big, powerful stride to get down the lines. The horse I was talking about before has the ideal stride for the 3'6" hunters, despite him being slow and 15.2 1/2 hh. We have to collect him so much for anything smaller. My TB is also a hunter who is 15.3, but has a stride on the smaller side, fortunately he's spirited enough to make the stride, but, while it's nice, he doesn't have the same effortless look that the first gelding has.
As a trainer, I would say pick one and stick to it, however personally I think she could excel in either/both. Her front leg action could be that of a hunter or simply a "tidy" jumper. The things you want for jumping is a calm temperment, but ability to judge fences and be quick with strides and knees at times. Hunters you would look more for the grace and beauty as well as quick knees and elasticity in striding. Try both and see which one you prefer and which she's better at then decide!
