The "T"

I've seen it done with a height slat, so I've improvised with a spare jump bar from an agility jump. If you picture the stride regulator (aka: piece of gutter) across the lane as the top of a "T", the jump bar forms the vertical piece running parallel to the lane. I've placed it slightly off center (toward the ball side) to get him to stride slightly to the right to get the angle for the turn. He seems to do this automatically if there isn't a ball, so I'll try doing this with and without the ball to see if it helps.
