Gaited horses = completely different than trotting horses
My gaited's all naturally tuck their head, lift the tail, arch the neck, and just kinda strut their stuff. That with riding just in the snaffle! I like the snaffles because it really allows them freedom to bob to the gait and move out. I don't have to worry that the slightest touch of the reins will cause them pressure in their mouths.
Shank bits ('traditional' gaited bits) are great if your horse has been training for years and moves at the most minuscule of cues. Those bits, in my opinion, are best left as flashy pieces for well trained horses.
Gaited horses are show offs really, they like to strut down the road and tell all the other horses "Look at me! I can gait
