Yes. Very true. A balance struck. I’ve blown a lot of these up knowing where the safety margin is and how far it can be pushed before failure. Heat treatment really is the key component of all this to get the belly to resist compression crush or failure. In my opinion bamboo properly heat treated is tough to beat pound for pound.
Have you managed to heat treat the bellies to the extent tnat the backs fail?
there were some test results published a few years back that indicated with certian species of Banboo, the core materiel (belly side) had compression qualities that overpowered the outside (back side) in bend tests.
