I was curious though, as to what other people are doing as far as training. I'm talking taking an unbroke horse, and finishing him out in whatever discipline he's suitable for.
For Divo (in brief):
Start with ground driving and working. Move up to under saddle work in a bosal hackamore. Then, move up to a two-rein, snaffle+hackamore, eventually finishing into the snaffle. When the tip of the iceberg has been reached, leap off and into the great Atlantic Curb Bit, laying Dressage and Driving foundation throughout the entire training period, starting with the hackamore.
Collection, softness, responsiveness, and delicacy of the mouth the ultimate goal.
Divo's five now, we won't be starting any saddle work until next spring. Plenty of time to play with him over the winter, get him accustomed to wearing tack and moving with the saddle.
