Tomorrow I'll be hanging my two new M2's on a couple of full metal bracket ceiling mounts, and was wondering if anyone who has done this before has some advice?

They'll be acting as my rear surrounds, and I've got some 35 pound rated ceiling anchors if I don't happen to find any joists in the spot where I'll be mounting them.
