Quoted from Budman:
Take a close look at Sterns official video showing highlights of each game. Notice the art blades on each model especially the Pro. That would have to be a Pro add on as I don’t see art blades included. So you could really mix and match blades on any model if you so desired. You could put colored blades on the Premium to brighten it up and dress up the Pro with LE blades.
LE blades not available as add-on unless you pull them off an LE game or have a connection at Stern.
