Hello Tom! I’ve gotten my hands on a set of 550c and they’re about the best clubs I’ve ever hit! According to alot of people I’m not supposed to be able to play blades, but I’m doing really well. I love them! The thing is, I fear they’re getting a little old, and I’ve been looking to buy a new set of irons, but I’ve yet to come across a modern club, blade or otherwise that I like more. So I looked up the origin of your clubs (I didn’t know much about you or your clubs beforehand tbh) just… Read more »

JOHAN Thanks very much for your message. It’s fun to hear that you discovered the 550C’s which were our very first forged carbon steel iron design that debuted in spring 2003 and stayed in the product line until 2008. The current cavity back forging that we offer is the 575MMC Cavity Back. It is forged from the same exact carbon steel as the 550C and all other manufacturing processes are the same from a metallurgical sense.

This is a fantastic iron for the better player wanting some forgiveness in his irons. Nice traditional look at address, great feel and performance. Best of all it can be matched with the 555M to provide a custom forged set where the golfer wants some forgiveness in the longer irons but the feel of a blade in the shorter irons.
