I was curious to see how various stallions are producing for dressage, and to see where Frits' bloodlines ended up: Rypke is the 4th ranked Sire and Tsjalling is the #1 ranked dam's sire! I guess he's got the right "stuff" :) Klass is a Jurjen x Tamme, both who ranked quite well in here, too!
I took the FHANA USDF All Breeds results from 2003-2005 plus the results from the FHS for 2005. I looked up their sires and dam's sires and here is what I found (the number indicates # of offspring listed in All Breeds Awards):
