You may want to check out panel-mates for the plywood - great product and rated one of the strongest fastners for plywood and panels. I have the .063 heavy duty aluminum panels (even over the garage door which is rated to 130) because the panels are rated much higher. The panels are very quick to install w/ a wing nut driver on the drill. So much easier and faster than the sidewalk bolts w/ lead anchors. Trust me I know...after last year, I had the anchors changed to panel-mates - at least 1/2 the installation time! My patio is covered w/ Armor Screen. During the peak of the storms last year with the wind blowing directly in, we sat out on the patio watching Jeanne and Francis. Armor Screen is also a great product for larger openings - it is actually rated as one of the strongest hurricane protection coverings.
