*raises hand* I have a Morgan!
I would have to say 1) Morgans! They are so versatile and come in so many shapes and sizes. Plus, one of the breed characteristics is tough hooves, so minimal hoof work needs to be done! Plus, they have fire and spirit, but are calm at the same time.
2) would be QH's or Paints
3) Eh...... Arabs aren't my favorites, as most I've worked with have been crazed, spooky hotheads-no saying they all are-, so I would probably go with a horse native to Australia for #3.
