I remember vaguely in your other thread you mentioned a budget in terms of the stud fee. As I'm sure you know, in horses, you really do get what you pay for, and if the stud fee is low, there's certainly a reason. Because of this, I would really steer clear of Simply Dangerous and The Silver Bandit. They don't seem to have done much, and there's just something I don't care for in their appearance, especially the Silver Bandit.
The other two studs are nice. A Strong Dollar has a nice pedigree on his Sire's side, but not a whole lot that is noteworthy on his Dam's. The Stonecutter is more well-rounded, lots of champions in there. He's actually closely related to my horse! :)
However, A Strong Dollar seems to have more titles under his belt. This is definitely a plus.
I'd ask for videos of these two, descriptions of temperament, etc. If it's possible, visit their farm... It would be immensely helpful to see the stallions in person.
Compare the temperament and confo to your mare. Maybe get back to us with some conformation shots of her, if you haven't already. (I don't remember from the last thread.)
MY pick from the studs on the site, if it were my mare, would hands-down be Generator's Silver Dollar. He's turned out some NICE horses in the past. Don't discount him just because he's a bit pricier. He's worth it!
