Another suggestion look around at futurities, a lot of them have donated stallions that you can get a half price breeding too.
We're in Canada and my trainer got a half price breeding out in Tenesse.
We're breeding my mare to Spooks Gotta Gun and through our provincial futurity instead of paying $3000 I'm paying $1500 which is a steal imo.
I agree with NRHAreiner on the studs, personally I would keep looking. Another thing to consider with the NCC bloodlines is I've heard you have to have a fairly strong mare to breed to them, and quite a few are a little bit spun. Don't get me wrong I love NCC but its something you need to consider.
If I had to pick Helluva Chex would be it, but I personally would continue looking. Depends on your mare I guess do you have any photos of her? How is she bred?
