Hitting hard and penetrating are 2 different things.

I am a carbon fan but have NOTHING against aluminum,in fact,I set my turkey bow up with aluminum.

UNLESS,you are using thick walled aluminium shafts,penetration doesn't do as well as carbons,ESPECIALLY when weight is equal,from my experience and many others.Too much flex in aluminum when hitting compared to carbon.


Of course,this is highly debated but I prefer the carbons when penetration is a concern.
