I almost bought a colt by their other stallion Dominator, so that's how I know of Grafenburg and the farm. They now stand a son of Grafenburg, Gastspelier. Good solid stallions, more old-style heavier types.
I was told by a couple of different breeders that he would be considered part of the "G" line as he went back to Grande.
My trainer has a broodmare by Grafenburg. Very solidly built horse. Fabulous movement. I had a lovely filly out of her by a "R" line stallion but lost her to colic last year. The mare has a 9 month old colt on the ground by a APHA stallion that is very solidly built, good mover and about as easy going as you could ask for.
I bought a colt at Indian Land Farms last year. Although Gastspieler is still listed on their website, I was under the impression that they were concentrating more on their other stallion Razmataz. When I went down last year to select a yearling, there was only one or two from Gastspieiler and the others were all by Razmataz.
