Without trying to stir up trouble, or hijack this poor guys thread; compression strength is a combination of compressive stiffness or modulus and maximum compressive strain. You're right Chris, ERC is not stiff in compression (neither is yew), but it has a high maximum compressive strain.
I'd say give an ERC bow a shot and you're opinion might change, or it might not and you'll just have more fodder for the cannon. Happy hunting ... for deer or bow wood
