RE: Training "Balls"
I dont "think" its excessive but distracting. Here's a thought. How about removing each skid tube. Replace it with a same diameter of a plastic tube. Instead of curling up the front end of it as normal, form it out to the side about 45degrees for an inch or so than then curl it up. Do this to each corner and would be sort of like a simple but wider gear. Sort of like your coat hangar thing.
Would eliminate many pieces. Would help prevent rollover. Sort of an intermediate setup when going from balls to stock
