yeah, i know. but i can't take the p&l off the ceiling = no time. i have WAY TOO MUCH on my plate as it is.
i used the 2" screws, and they worked fine. i went in the attic and drilled holes on the north side of the joists. so my screws hit the joists. sides, the few times i missed a joist, i could easily tell and put one next to it.
