I will check in case it was a typo on the durability, was getting a little crazy eyed, but as far as specific gravity
The specific gravity (SG) of wood is a measure of the amount of structural material a tree species allocates to support and strength. Differentiating wood specific gravity from wood density, drying wood samples at temperatures below 100°C and the resulting moisture content complications, and improperly measuring wood volumes.
in a nut shell its related to the density of the wood and will effect the float and how much lead it would take to sink the piece of wood.
I am working on a calculator that will be a best guess as to how much lead you would need to sink a piece of wood, for example a 3"x 1" piece of AYC will sink with around 1.25 oz of lead
