Will you be gigging with this kit? Whether or not I drilled a kick would depend on if I intended to gig a lot with it. The advantage of a tom "tree" is consistency and ease of set-up and tear down. If the kit stays set up at home or is gigged only occasionally I would just use stands. Unless your desire for the tree is beyond the practical side of things and you prefer the look as well. In that case I would just drill it and be done with it. I've read some stories about that Atlas thing coming loose all the time. And it's such a huge hunk of metal.
