I agree. Marbach's horses are all worked before they go in the breeding shed. Mares are driven, stallions ridden, do their performance test, 100 days of dressage, jumping and cross country, rideability , character, and what's called a strange rider test(one rider is responsible for the stallion during the 100 days.
This is what they're being used for, riding.
And Gharib was also licensed for Trakehner, which is very hard to achieve, Trakehner folks are uber picky with what they allow.
Unfortunately, the stallion licensing is not mandatory anymore, since WAHO says no purebred should be discriminated against......
