He was sensitive & opinionated. As one BNT said in a clinic, he was like a violin–when you did things badly, it was horrible, but when you did it right it was phenomonal.[/QUOTE]
I have owned a Hungarian Sportlo (full Hungarian H mare, European Warmblood sire) for about 4 years and have had the same experience as Salty. He was sired by Guigan de Lully, SWB, who is known for volatile offspring (as soon as they hear the sire, BNT’s ask me how many times I’ve been bucked off - answer - several!).
The following website gives lots of info and explains the difference in registries.

Mine is talented and definitely not a beginner horse but this is only my experience (and he had a bad start, hard to know how much that influenced his future behaviour) - I have not met one other Hungarian horse to compare him to. He is 16 hands and quite compact with lovely movement and a beautiful head. I compete dressage.
Good luck - I look forward to hearing how it went!
