Weighted iron set

1. A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees and a first club head mass, a second club head having a loft of between about 26 and 35 degrees and a second club head mass, and a third club head having a loft of about 36 degrees or greater and a third club head mass,

the first club head comprising:

a body made of steel comprising a heel, a toe, a topline, a sole, a hosel, a front face insert made of steel and a back wall forming a hollow cavity therebetween,

a toe weight member formed of tungsten and coupled to a toe portion of the hollow cavity that comprises 25%-35% of the first club head mass; and

a heel weight member formed of tungsten and coupled into a hosel cavity formed in a lower portion of the hosel, the heel weight member comprising 5%-10% of the first club head mass, wherein the heel weight member is enclosed in the hosel cavity by a steel cover member that forms at least a portion of the hosel.

2. The set of golf clubs of claim 1 , wherein the second club head comprises:

a second body made of steel comprising a second heel, a second toe, a second topline, a second sole, a second hosel, a second front face insert made of steel and a second back wall forming a second hollow cavity therebetween, and

a second toe weight member formed of tungsten and coupled to a second toe portion of the second hollow cavity that comprises 25%-35% of the second club head mass.

3. The set of golf clubs of claim 2 , wherein the first toe weight member and the second toe weight member are at least 65 grams each.

4. The set of golf clubs of claim 2 , wherein the first club head and the second club head have a Moment of Inertia about the y-axis, extending vertically through a face center, of greater than 250 kg-mm 2 .

5. The set of golf clubs of claim 1 , wherein the first club head has a Center of Gravity that is less than 18 mm from a ground surface when the club head is in the standard address position and is greater than 6 mm from a face center toward the back surface.

6. The set of golf clubs of claim 1 , wherein the first club head has a Moment of Inertia about the y-axis of greater than 250 kg-mm 2 and a blade length of less than 82 mm.

7. A set of golf clubs comprising at least three first club heads having a loft between about 15 and 25 degrees and first club head masses, at least three second club heads having a loft of between about 26 and 35 degrees and second club head masses, and a third club head having a loft of about 36 degrees or greater and a third club head mass, each of the first club heads comprising:

a body made of steel comprising a heel, a toe, a topline, a sole, a hosel, a front face insert made of steel and a back wall forming a hollow body having a first blade length,

a toe weight member formed of tungsten and coupled to a lower toe portion of the hollow body that comprises 25%-35% of the first club head mass; and

a heel weight member formed of tungsten and coupled a lower hosel portion of the body that comprises 5%-10% of the first club head mass;

wherein the combined mass of the toe weight members and the heel weight members for the first club heads increases with loft;

wherein the first club heads have a Center of Gravity that is less than 18 mm from a ground surface when the club head is in the standard address position and a Moment of Inertia about the y-axis of greater than 250 kg-mm 2 ; and

wherein at least one of the first club heads' Moment of Inertia about the y-axis, which extends vertically through a face center of the first club head, is greater than a second Moment of Inertia about the y-axis which extends vertically through a face center of at least one of the second club heads and less than a third Moment of Inertia about the y-axis which extends vertically through a face center of the third club head.

8. The set of golf clubs of claim 7 , wherein the first blade lengths are less than 82 mm.

9. The set of golf clubs of claim 8 , wherein the first club heads have a Moment of Inertia about the y-axis to blade length ratio of greater than 3 kg-mm.

10. The set of golf clubs of claim 9 , wherein the Center of Gravity depth from the face center for the first club heads are almost 1/10 the first blade length.

11. The set of golf clubs of claim 7 , wherein the second club heads have second Center of Gravities that are less than 19 mm from a ground surface when the club head is in the standard address position and the third club head has a third Center of Gravity that is less than 19 mm from a ground surface when the club head is in the standard address position.

12. The set of golf clubs of claim 7 , wherein each of the club heads has a Center of Gravity height from the ground that increases with loft through the set.

13. The set of golf clubs of claim 7 , wherein the Moment of Inertia about the y-axis for the first club heads increases with loft.
