I'm all for trying new things but my honest reaction to this is that it's probably the worst "false bottom" idea I've heard of. I know, bah humbug. I cringe every time I have to take my false bottom out of the tun to hose the grain off of it. That's one piece of stainless. If I had to juggle 10 pounds of ball bearings after every brew day, which will inevitably fall and roll all over the place, I'd probably drink the Budweiser cans that my wife insists on keeping in the fridge rather than brew. I guess I'm feeling especially cynical today.
