What angle do you guys use for your kickboards?[/QUOTE]
Straight vertical.
I have seen some spectacular wrecks with horses missing a turn and climbing those slanted walls.
In fact, I ended up with a broken leg, courtesy of a colt I was starting that didn’t quite get his legs turning in our oval indoor and hit close to the bottom of the sliding wall and fell into the wall, mashing my leg in there.
It is mere physics, a large mass like horses are, supported by four legs under it, if it hits with any momentum on a wall at that angle with the legs close to it, it can’t do but slide into it.
Similar to when our feet go out from under us on ice, a wipeout.
The reason people started slanting walls in riding arenas is under the impression that would give more room for the horse’s upper body and rider’s legs if the horse was close to the bottom, which is right.
A guess what can be worse, if a horse steps on that slanting wall and a very sudden wipeout, or getting your leg scratched along the wall.
