It for sure would be a mover. Don West a trainer-breeder of peruvian pasos started crossing them to gaited mountain horses to increase size and give them a little better temperment. Brenda Imus another trainer of gaited horses crosses TWH's to appylosas to get Walkalosa. Imus also claims that she doesnt care what breed a horse is she can tell his gait just by looking at the conformation. I think there is something to this but don't by off on everything she tries to sell, and she does try to sell.. and sell... and sell... most of her training dvds you buy are more like informercials to buy more of her stuff
...some of her stuff is good some is just a bunch of hooy.
I also have a friend who is breeding Foxtrotter mares to Jacks to get gaited mules...Man are they cute.. He keeps tring to get Maureen and I to breed our rocky mountain horses to the jack and will buy every mule that we want to sell.
