Without having the opportunity to examine and measure the new iron, it is difficult to comment on what the characteristics may or may not actually be. Tungsten is roughly twice as heavy as steel, so generally you use it to manipulate or control weight distribution. That is how we use it. By using it to get the cg in a good position, you could improve the feel. Generally, because irons of that kind of design have such a short blade length and long hosel, you would want the tungsten towards the toe and low to offset the negative effects of these features, hopefully moving the cg closer to the center and lower in the face. Putting tungsten in the toe, heel and center can work, but you have to still maintain the proper head weight, so the amounts you could actually put in all three places is generally not a net positive. Just depends on the material the head is made from, the size of he head, etc. on how much tungsten can be used. Hopefully I will get a chance to measure it. Should be interesting.
