Down here we don't use moldboards. The thick gooey clay won't allow it. Have to have a rolling disc and if in the spring you had better have your scrapers in good shape, unless you are chiseling, or running a sweep for cultivating which is done when things dry out somewhat.
So, if you are going to break the sod so to speak it's plowing to us regardless of what you use. I know you guys in the sandy loams run 16-6's and all that, rolling the sod over and all, but down here we cut the surface vegetation into the top soil which is what the disc does and upon reading on the www, back in 1920 some guy up there pioneered the offset but he only had one gang on the original plow with no counter wheel.
We aren't fortunate enough to have 6' of top soil like I'm told Iowa and other places up there have. This land was cottoned to death for 50 some odd years. The easiest way to remove stubble was to burn it off, rather than plow it back in developing some humous and improving the soil. Besides after the picker or pickers before the advent of the motorized picker finishes, there isn't much stubble anyway. So what's left is solid clay, rock hard in the summer and sinkhole goo in the winter.
There is a different "plow" we use down here and it's offset also but only has 1 row of as many as 16 24" discs on it. It rides out away from the tractor at the tail end and there is a huge wheel weighing who knows how much to counter the torque there. New they came with JD green paint. Again the rolling wheel with the scraper. Commercial/multi field operation guys don't use it as road transportation is a problem. Much easier to run a big disc with batwings and go over the field a couple of times to break it up. 1 trip operation.
So forgive me for "cussin" but we don't know any better. Grin.
