Lovely mare (I watched a video)!! I would be riding her if it were me:)
I too really like Soprano’s blood lines. I don’t know much about what he throws himself however, but agree Contender is a fabulous line.
I think Liberty Gold is a highly underutilized stallion and brings a good combination of the W and L lines together. He has produced a super high percentage of Elite mares, highly rideable, good conformation and gaits. Had he stayed in Germany I think we would have seen an abundance of good offspring of his.
I have bred one Rousseau and he has matured into a lovely riding horse. With my mare he added height, length of leg with a lot of bone and more suspension to the trot. He has a great temperament and willingness to work under saddle (he is now 4). His owner is a successful FEI AA rider who feels he will take her well up the levels. I think he is one of the most proven stallions we have here in NA so if he fits your mare conformationally you can’t go wrong with him.
The same above mare has also been bred to Wolkentanz II and produced a nice gelding with three solid gaits (maybe not as much suspension as the Rousseau) and very nicely put together. His owner states he is sensitive but sensible and will start his under saddle career next year. I think conformationally the WII gelding is nicer conformed than the Rousseau, but the Rousseau has a flashier trot. Along with Rousseau he too is a highly proven stallion in NA.
I now have a Buddenbrock filly out of the above mare. She is only 3 weeks old but the “prettiest” foal I have ever had (despite some vascular issue due to trauma of a rear leg that i am hoping to surgically repair. Thankfully it does not cause her any discomfort or lameness). She is very tall and leggy, beautiful head and neck, great loin. All this for sure being brought through the Trak blood. Of course I cannot say anything about ride ability, although she is a very confident and super friendly filly. He does not have the name recognition of the above stallions outside the Trak world but has proven that he can produce upper level dressage and eventing horses though his offspring in Europe.
Other dressage stallions in NA that I keep on my short list (of various registries) are Benidetto, Royal Prince, UB40, Viva Voltaire, Bugatti Hilltop, Schwartzenegger, Sir Sinclair.
