With all new technologies cad etc far as weight do you need to put tungsten in the toe to bring up Moi for more stability or shape the toe in a way different from the heel that you don’t have to put a actual tungsten in the  toe is there a difference between the two and the screw weight I see in the center is that for feel or cg location? Irons with tungsten are they better than irons that don’t have weight?
