We’re talking about compression wood here. That means a backing can be used to demonstrate the best compression woods. Crushing strength should not come inti plat at all here. That is for core woods in composites. Black locust is not a contender. Osage is, but the best compression woods can handle the most amount of bend without taking set. So lighter woods good in compression are best. Yew is great, but I would argue the best are much lighter. Woods with very low sg around 30-40 with a true backing to take all the compression. Specifically I think incense cedar and juniper are the best compression woods.
