Ekoa fibers have impressive elongation before break properties such that the high toughness bioresin would likely give first and only after a significant impact. This is opposed to carbon, which while very strong will break before/with the resin. Our composite jumbo guitar El Capitan's unibody is thus super robust and folks who have handled our Clara concert ukulele can attest to that. All in all, extra strong as typical with Blackbird construction.
