I don't own an Appy of any type, but if I did, I would lean towards the foundation type. I like Appaloosas to look like Appaloosas and Quarter Horses to look like Quarter Horses.
I think it's sad to look through an Appaloosa magazine and see tons of solid horses that look just like Quarter Horses, complete with HYPP bloodlines and very little color.
Now I like Quarter Horses. But why do we want Appaloosas to look like Quarter Horses? If you don't like color then just stick to Quarter Horses instead of changing an entire breed to look like Quarter Horses? There is a similar thing going on with Paints. Tons of solid horses. The Paint Horse Journal looks like the Quarter Horse Journal. And all the halter horses are these huge, beefy HYPP types.
And Arabians, they need not look like Saddlebreds. And Morgans, they need not look like Arabians. And Quarter Horses need not look like Thoroughbreds.
I like breeds more like the way they used to be......before they all started trying to look like one another. I like a an Araby Arab, a Appaloosa-y Appaloosa, a bulldog Quarter Horse, and a chunky Morgan. And Paints and Appies with color. I know solids will crop up, but I swear, there is so much Quarter Horse blood in the Paints and Appies that they are loosing the color. At least the ones in the breed journals seem to be.
