Robertson Screws? Drywall Screws?

[NW Modeling List]

 While helping a friend build the benchwork for his Milwaukee layout we started with Philips head drywall screws then switched about 1/4 of the way through to Square drive screws. The Square drives were far superior in my opinion. We also predrilled and countersunk everything. The screws came from a place called McFeely's that specializes in square drives.

I've used nothing but drywall screws of varying lengths - mainly 2" and 2 1/2".  Work great, go in easy and a lot cheaper than "normal wood screws".  Also less apt to strip the head if you have to change something (if?????).
