Morning everyone. Just joined forum and it's my first post. Need advice...I play calloway 2002 big Bertha irons steel regular shafts. Keep thinking to upgrade but these are my late fathers and play well with them. Don't hit them miles but know my yardages (140 yds with 8 iron). Is it worth me upgrading to newer set? Love the big Bertha chunky look at address and the offset. I have a set of mizuno t zoid true irons, brand new in garage waiting for me to give them a try also. As you can see I like the older clubs. Was looking at ping eye2 or zings....any ideas? Thanks guys.
