I wouldn't fret much over the decision between 66" and 72".  Pick one.  Personally, I'd go with the 6' BB since it allows your hitch to sway a bit and still covers your tire track well.  Seems like a more standard size that could be bought cheaper too.  Either one will be better suited than the 7' blade you're using.
I almost never drop the scarifiers down. Certainly don't on the driveway.
