Crazy guess, but since basswood is so soft and absorbent, wouldn't stabilizing it make it a very good performer? I assume that the strength of stabilized materials comes from the resin, so the more easily the material can get saturated, the better. Micarta and G10 are almost indestructible, but the commonly used hard woods, which have a tough time getting impregnated with resin, still crack along the grain when they're stabilized.
