I got the 3 & 5 component heads years ago when Key golf Golf Co. went out of business, they were dam near giving these away. Always figured I'd use them for a season and upgrade to some brand name clubs later. Well, nothing has ever knocked these out of my bag. I didn't know anything about them other than they were cheap. So I did some reasearch and found out why I hit these so long and so well. They are made of 15-5 steel and use an elyptical face support, similar to what was used in the taylormde r7. By re- positioning the weights you can even change the ball flight. After years of use pounding balls they show very little damage. The quality is way better than I ever expected. If you can still find any of these, give them a try. You will be suprised.
