Also, I am really not being rude with this next statement, just blunt. I personally don't think he would be a good quality producing stud. His confo is not terribly impressive and his bloodlines are not eye popping. There are so many really good studs out there with spectacular bloodlines. He may make a nice stud but I bet he would make a spectacular gelding. Keep in mind that this is just my opinion.
Since he already has a bit of a behavior problem, from what you have said, I would not want this trait passed on.
Again, he is a lovely horse, but in my eyes not stud quality.
