I have no idea what these FFFs you're speaking of are, but aside from that, since you got a versicolor, it's going to need more height than a deli cup can offer, as Jeff said. I've personally never dealt with Jamie (simply because I'm from the great white North lol) but I've heard nothing but good things about her. Her starter kit looks very cool, so you can give that a shot or go to your local petshop, get a tall Kritter Keeper type enclosure (on a side note - the tall 1 gallon jugs you can find at Wal-Mart, with coco fiber at the bottom and a piece of cork bark leaned agains the side works very nicely for arboreals. Just drill or melt holes in the side for ventilation). Whatever you do, the versicolors like a lot of humidity and need a lot of ventilation too.
That being said, since it's arboreal and won't be spending much time on the substrate, you can afford to add vermiculite to hold the humidity better. A lot of tarantulas don't like walking on vermiculite because it sticks to them (like Jeff said), but if it's arboreal, then it's no biggie![]()
