Re dressage stallions on jumper mares. My friend has a fantastic fancy hunter prospect and she is by Juventus out of a TB mare. Even though he's deceased and not "en vogue" I'm strongly considering him for my own mare after seeing her foals (oldest is 3). I was really impressed (she's had 3 and each time he stamped the mare in a positive way). Mine is also very modern in type however (with regard to using a heavier, deceased stallion).
Random, but I particularly like Solomon's Der Graf-Solidarity foals (Galoubet) a lot too.
