Ecaussinnes Collection

U’RE Joni’s Boy is sired by Stakkato Gold, a reference in German show jumping breeding. Named Hanoverian Stallion of the Year in 2015, he also performed successfully at 4* level under Jan Sprehe before establishing himself as an exceptional sire. Many of his offspring compete at 5* level, including Stargold (winner of the CSIO5* Grand Prix of Aachen 2023 with Marcus Ehning), Solid Gold Z (World Champion of 7-year-olds and World Cup winner with Christian Ahlmann), and ESI Rocky (European Young Rider Champion 2023).

On the dam side, Cooper van Heffinck adds the respect and power for which his progeny are widely recognized.
