Ok, here are some "sturdy" props.
However, I agree with other posts about carbon props and planes prone to ground strikes. I have carbon fiber "show" props, but for everyday flying, I stick with wood. Cranks are easier to damage than one would think. It may be almost undetectable, but RPMs will suffer, and the vibration will be damaging to other components, possibly leading to failures. Wood props are very forgiving, for the most part.
