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?
Swing weight and swing balance are totally 2 different items and you can talk till your blue in the face about the difference. Kenneth Smith’s using balance scale is the only way you can get the correct balance.of the club. It has a 12″ length on each side of the fulcrum not 14″- 10″. Balance is the feel co the club at the moment of enertha, the start of the down swing. Taking the iron that you hit the best and make all the irons with the same balance point. The most successful golfers in the 40’sand 50’s had Kenneth Smith adjust ther clubs to this system.
In your description of the two different clubs, although the swingweight is the same, because has a lot of butt weight and and heavier head and the other does not, they will not feel the same. In our schools, we use a example of two clubs with the exactly the same swingweight, but one of them weighs 5 pounds and the other weights 10 ounces. So obviously there are different ways to manipulate the weight distribution to get the swingweight scale to a reading. Swingweight should be used as a reference for consistency and feel, for sure, but the overall weight and the weight distribution of the club plays a big role in how the overall club will feel. As far as balance point, there is no one “optimal” balance point. The weight of the components and the distribution of the weight in the shaft, along with the length of the club will determine where the balance point is. Once you find the feel of a club you like, that’s what you should try to duplicate throughout the set. Obviously the feel of a driver and the feel of irons in a set will be different, but there should be a “feel” in each of your clubs that you are comfortable with. You just have to experiment and find it.
