I floated my Bold cabinets. I knew I wouldn't be getting them to capacity, so I was not too concerned. I have had them up for a year now, with no issues.
I used a 2x4 ledger attached to the wall with Spax lags into the wall studs, then used 1/8" flat bar inside the top edge of the cabinet to spread the load of the lags there. So far, so good. I will be sure to share pictures if it fails spectacularly. The cabinets won't be filled to anywhere near their claimed capacity, and the work surface will be more for fine work than banging and heavy stuff.
