At his proving test, Zuidhorn scored an impressive list of marks, with four 9\\\'s and a 10 for his training report, making him the Champion of his year (1994) when graded in The Netherlands. He was described as having enormous talent in both dressage and show jumping and completed at ZZ-dressage and ZZ-show jumping. All his gaits are rhythmical and balanced and he had great jumping capacity, with a smooth and skilful technique. He has shown many fine products that received first premiums and/or became champions. His strong hereditary conformation capacity is demonstrated by the high percentage of ster premiums of his offspring. But apart from a good conformation, Zuidhorn also passes on his performance power.
