At fair this summer, I'm hoping to show Lenox in some Western Pleasure walk-trot and Western Horsemanship walk-trot. Her canter still needs work, and once I move up from the walk-trot classes I can't go back down. Anyway, since she's over 5 (12) she has to be ridden in a curb bit. Right now I ride her with contact in a Mylers D-ring, but she supposedly neck reins a little. I'm curious as to when I switch her over from a snaffle to a curb, when I start riding her one-handed, and what bit to switch her to when I do switch to a curb. Thanks!
P.S. The bridle she came with is good-quality, but older and REALLY stiff. Like, if I hold the end of the rein up, the entire rein will stand up straight, with no bend. Any idea how to loosen it up? The oil I usually use did nothing.
