I'm about ready to start framing my primary layout (just 7' x 10'), once this deep freeze passes. The book I'm reading about benchwork recommends using drywall screws to affix the frame together. The 4' x 8' I put together last fall I used nails. Are screws that much better for something like this??? This may be a stupid question, but I'm still just a beginner, so . . . .
