This is Joaquin Estaban, one of those Mahoma/Hilachas crosses. I think the horse probably is more Mahoma and transmits Mahoma moreso than Hilachas, so he's going under the Mahoma thread. I find the Mahoma lines to be  well-conformed for the most part and solid gaiters.

Mahoma

It was said of Mahoma by his original owner in the U.S.A. that he hated being ridden and would pitch a fit the whole time, and he really had to be held in tightly. He was extremely barn sour. When he was going to be ridden, he would have so much anxiety that he would defacate numerous times. I have a Mahoma grandaughter and a great grandson, and they both are like this. My Mahoma granddaughter has a fear of being too close to other horses and getting trapped or cornered. My great grandson does not like to go into any situation where he might be trapped with no way out, and he is a "defacator extraordinaire" when he thinks he's going to be ridden. It's not his favorite thing to do, nor is it my Mahoma granddaughter's. It was also said of Mahoma that he had perfect conformation, which I don't think his conformation was "perfect." If I could fault him, it might be in the hind legs, though much better conformed than Hilachas.
