I notice the advantages are the shot is quieter. Just seems the wood soaks up that noise, where aluminum is an excellent conductor for vibrations and ossiclates more. Also, wood seems to be more forgiving in spine.

But wood is dynamic, where it will change spine over its life. You have to hand staighten them and often. Aluminums you don't. Points can be a pain to keep on, espeically if you target practice in cold weather.
