I wonder if the jerky stroke and violent indexing add to the roughness, or could it be that wide angel-wing agitator? I do remember my mom complaining about the White-Westinghouse TL tearing things up, however, it still had the metal tub and rear-mounted recirculating filter and wasn't one of the newer, crappy, plastic, "clothes-cutting-tub" models. It did agitate fast, but was very smooth.
Yes, I was very surprised not seeing any turnover, but I don't remember any of the indexing-tub machines I used turning over or cleaning well (especially the Frigi-Lux...YUK), which is one of the reason's I'm not partial to them; the agitators travel around in a circle with each stroke. The Wizard's splashy, sloshy action convinces me otherwise (the Wizard and Westinghouse are the only indexing tub machines I would use), and from Robert's statements the Wizard seems to wash pretty well even with the indexing tub.
As another comment, love the Wizard's selector switches! Cottons...SNAP! Cold Water...CLUNK!
