Yes, I slowed my motors to keep the "arrows" in the "rotating quiver," too - and my wire wheels are staying together much better.
Note: Heavier wires tend to release at higher speeds - the fine wires seem to stay put at higher speeds..... Although, cheap wheels shed their sharps at the same slower speeds that the German twisty wheels stay intact at ....
