I have seen a few yearling's by Changeover and they were good types like himself, i've only seen one during the breaking in stage and it was a natural pacer from day one. I was at Nevele R a couple of year's ago and i got a surprise as to how big and well put together he was. The other thing to note would be that stallion's at stud by ITP have done a great job such as Christian Cullen and Courage Under Fire so one would expect to see Changeover get his fair share of winner's, he is at a reasonable price so he might be worth a go with your mare.
