Good stuff Dave!  Although the carpenter in me wants to let you know that using 6" screws is not a good idea as you have a high likelihood of running them into something traversing your joists. Think water lines, power lines, etc.  A 3" screw is far stronger than you think. I would recommend using nothing more than that to minimize the risks of hitting something in the framing.
