People in my area LOVED my stallion, and I have shown him heavily from age 3 to present (age 6), but with our current market, I decided to geld him (after 1 gorgeous colt that we are keeping and gelding), because he is much more marketable as a lesson horse or horse for a kid to lease than he is as a breeding stallion because of the lack of breeding/young horse purchase in our area and the current market.
We have a mare with bloodlines that I personally LOVE, and I DO want to breed her again (she is the one who had the colt by my APHA stud), but I want to spend a few years finishing her training and competing on her (she is gorgeous and has a lot of talent) before breeding her again. When we breed her again, we will take our time to find a great stud, and keep the foal.
I just wanted to share my own personal epiphanies about breeding...I don't regret anything I have done, but my thinking has just evolved as I have seen where the breeding market for horses is at.
Good luck with your decision...take your time making them (picking the right stud, when to breed, etc.)
