I really like how die guy used the simpson strong ties, and I think that my lowes has them so that is one that is next on my shopping list. What type of screws are needed? Galvanized or stainless? I would think that galvanized would be stronger, but stainless would last longer. The strong ties are galvanized, so would galvanized work for all the hardware in a mod? Before seeing his mod I was just going to get long screws and screw through the 2x2's, this way seems much stronger. I really want to do this right the first time.
