I particularly think Colored warmbloods and those gorgeous double registered Sabino paint TB x's..... But remember, any one can be a breeder - but for a profitable breeding, you should always breed for quality, temperment, conformation, and athleticism. If you don't breed for quality, your horses won't ever be worth much. Plus, you have to breed horses that there are a demanding market for - like QUALITY colored sporthorses..... :) I'd love to breed those!!!
Gallop as if you'll die tomorrow, jump as if you'll live forever.
