Well, except for the fact that I'm the king of bad luck, so I always err on the side of caution.

The M60 may be a better bet but I can't say whether it would acoustically disappear as well as the M5.
My flooring is carpeted. But it would certainly help knowing how speakers like the M5HP would sound crossed with two pairs of subs. And would I'd still be better off with M60 or M80? Any thoughts on this?
