Indeed, easy to produce and maintain. Precisely as Leo wanted everything he made.
To reply to some other comments:
No, I've never installed one, but did have two identical basses, one with, one without. The BBOT was every bit as good as the BAII, or the BAII was not any better than the BBOT - whichever way you care to put it.
Collapsing saddles and perishing springs is usually down to poor maintenance, not poor manufacture, although self-loosening grub screws is something I've been afflicted with just the once, easily remedied by improving the admittedly rather poor factory setup (something Fender still are not that good at, even on high-end stuff, although the transatlantic journey probably doesn't help much...).
I'm not in any way saying the BAII is a bad bridge - it isn't. But neither is it such a piece of uber-engineering that the BBOT MUST be replaced by it. Fitting them as standard to the MKII Highway Ones seemed an upgrade without a purpose, but if I had one of those, I wouldn't take the BAII off - wouldn't be worth the effort!
