I personally went with floorstanders (the RP-8000F by Klipsch) with the intention of most likely adding subs later on to extend the lower end. Comparing the cost of OK'ish stands + the bookshelf version, and the size required for both versions, I came to the conclusion that even if I were to cut some of the lower end extension from what the floorstanders can do, it'd still be easier and cheaper to go with the floorstanders.
Besides, until I do get around to purchasing those subs, the floorstanders will sound better than the bookshelves.
I guess that in a couple of years, when I have swapped my equipment around a few times, I will regret going with floorstanders due to the sheer weight of them.
