My reiners all trail ride as well. I never have sliders on until a little bit before the show and I won't do any real big trail rides until the sliders are off. I am notorious, however, for wanting to run like hell all the time. That's my biggest flaw. I find it hard to rate myself. But I just chant to myself and use will power to not run my reiners with sliders on. And if I do find a decent place to run, I once again use the decent will power I was given to not run fast. I generally will just trot on decent ground if I have sliders. If I don't have sliders I will go on ahead and just lope and transition down to a walk before I stop.
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
