@jenbanim From an actual physics standpoint it probably should break but having it indestructible you would open more options in terms of tricks. Perhaps make certain terrain "bouncy"? The reason it was a "trick" is that you can go much more quickly without losing control when the ball is spinning around because you can just purge and reset.
That said being able to drop it even if it breaks just sort of makes sense given you already control the tractor beam and if there is turret breaking ...
