OK, here's your chance...
What would you do if you were the owners of Copy That?
1. Treat and rehabilitate with view to return to racing June or July?
2. Retire to stud?
I would opt for #2, I give you the tip. Retire him to stud now. Rehabilitate at stud farm for new season. I think it is too risky to plan a return to racing. The horse will be a year older and I think there are some handy horses coming up, many a lot tougher than Copy That. Also in rated races he will draw bad given his record and will struggle as again he is not tough enough to do it hard.
Just my thoughts. What would you do?
