A friend of mine has a set of Cleveland Launcher hybrid/irons.   He recently broke the 5 iron, and asked me to replace it.  Here is the information he sent me (I assume he copied this info off the shaft itself)….Can you recommend a graphite iron shaft that would match these specs?   I could hand sand a .370 shaft down to .355, if necessary…..
