I'd ask: why would you *not* go with floorstanders? The two reasons I see most often are: the other half objects, and there's not enough space. You said you have lots of space and frankly floorstanders often take up just as much floor space as standmounts on stands.
Though there is sometimes another reason: cost. And another: portability for buying and selling and moving to a new house. But floorstanders are evidence that you're serious about sound.
