People misunderstand balance. I've written on in here, quite a bit.
Consider using real, calibrated, balancing equipment and posting the results in IPS. I think you'll find that Listeroids, even when balanced to the point that they don't hop or shuffle around the floor, are still horribly balanced. With minimum IPS readings in the 0.7 range, under no load conditions. Folks, that's horrible.
Video makes the engine look smooth. Seeing it, and better than that, measuring it, in real life proves my point. These engines are not, and never will be smooth.
