Certainly don't switch to carbon for the lighter weight. I don't think light weightarrows are a good choice for hunting. I wouldn't go much below 425 grains (my humble opinion). Personally, I lean toward the heavier carbon arrows, not the super light ones. My carbon arrows are heavier than many aluminums ofsimilar spine,and I'd like to keep it that way. I think the biggest advantage to carbon is durability.
