Since I've seen horn and snakewood overlay "snap in half" at the string groove, I use nothing but the densest woods. I like skinny tips, narrower than ½", so there's not much wood to hold my string in place. I need it to hold, and not worry about the string denting the overlay. WRC is way too soft for me liking. I would have to compensate the weak wood by making my limbtips much wider - not desirable for me.
