Here's an entirely different solution. We call them "softies". All they are is a short (6') endless sling made from 4" webbing. Use them in a basket configuration, as shown, and you spread out the load over 8" so it doesn't dig into the timber. And they don't slip and fall out like edge protectors do. They also pull from the center, so they don't try to twist the timbers as you tighten the straps.
