As for bracers having good synergy with BW, you're absolutely right - when it's available, the aspect is certainly going to be stronger than the focus reduction from the belt. The difference just is, belt is up *every* BW, making it a reliable outcome every time, rather than the aspect, which will be up every ~3 BW's with bracers, and every ~4 without, assuming no convergence (which I expect to be outclassed by heroic tomb trinkets, unless you've got a VERY juicy one).
As for specific fights and PTR tests, I've done none of them, so I wouldn't know offhand where I'd expect to use the various stuff. Belt+Ring just seems like it'd be the most versatile setup; It allows for the most reliable burst (more DF, more focus, every BW is powerful due to belt rather than only every 3 due to bracers), it has the best AOE potential (due to DF uptime+focus to spend on multishots; 122% attack speed > 100% more damage, because 122 is bigger than 100), and it's not far behind pure single target (in fairness, none of the combos are).
