I have only used the metal Knap & Vogt -type standards and clips for adjustable shelving in the past. They work well and support a reasonable amount of weight. I was going to use 6 standards (3 on each side) for these shelves, which is probably overkill.
But lately I have gotten interested in the 5mm pin supports. I know that the strength of these depends on several factors, one being the type of wood used. So, for those who have used these things, how will they do in, say, baltic birch plywood? Are the metal track/standards going to be significantly stronger? Shelves will be 3/4" plywood.
Benefits of pin shelving include not having to dado for the metal standards and a neater overall appearance.
Happy New Year!
