Any of the Weltmeyer kids and grandkids can be more sensitive, but they’re far from stupid nuts. I have a White Star daughter and she is very sensitive; however, she does not have a propensity to rear. There is a difference between sensitive and crazy.
I have a Wolkentanz I granddaughter. She is light of foot, pleasing movement, superior engine, super-duper brain. But she is more sensitive than her mother was, who is also mine. She has jump. Both top and bottom of her pedigree is a mixture of show jump and dressage. Thus, her movement makes her good enough for the dressage ring too.
I, personally, LOVE Wolkentanz II. He has superb manners. If you’re ever in the area, phone them to come for a visit and they will gladly present him to you for a personal introduction. His offspring, as a whole, tend to be quite stamped by him. He has a very strong prepotency for improving topline, shoulder, neck connection and a good engine. He also improves legs and gaits. His breeding score is still well over 170 and he is still placed in the top 10 for Hanoverian stallions with riding type worldwide - he still beats Sandro Hit and Lauries Crusador in this regard. He is still in the top 15 worldwide for Hanoverian stallions as a dressage sire, as recently as 2009.
He has a good mind and most of his foals have good minds.
Like ANY bloodline in this world, there are always a few exceptions to the rule where for some reason that particular mix of genetics between sire and dam produces a crazy nelly.
But this is the exception, NOT the rule with Wolkentanz II. Even since being imported to Canada, he is still highly praised by both the Hanoverian Verband and Oldenburg Verband for his quality of get and by riders around the world for quality of movement, athleticism and their propensity for winning in the dressage arena. Last year, Oldenburg Verband awarded Wolkentanz II, once again, as having a very high percentage of premium foals. This is pretty darn impressive. He is very, very, very consistent.
A few of his foals jump too. Remember, he descends from World Cup who was a Grand Prix show jumper. He produced Weltmeyer only because SPS Anka was a very powerful A-line dressage mare. Even still, Weltmeyer produced both jump and dressage and the trend continues down the line. My White Star mare was used for dressage, but she has clearly demonstrated the lovely ability to clear my 5’6" fences with room to spare when she wants to. Fortunately, she tends to be rather content to stay home.
