Obviously, the feel of a club when you pick is important. If you have two 5 irons that have the exact same swingweight, will they have the same feel, will they have the same balance point?  Let’s say one of the clubs has a heavy head, light shaft, light grip, and a lot of butt weight is added to make it a D2. The other club is made with better matching components where little or no tip/butt weight is needed to make it a D2. Will these two clubs feel the same in your hands, will they play differently, will they have the same balance point?  Where on the shaft is the optimal balance point?
