Titan, good stuff, you have to hit them to get it, but unfortunatly that part seems difficult in many places. OEM I have had the Di11's out for a ton of range sessions and rounds and I will post some pics today of the finish of these clubs. I think they are holding up really well.
So far mine are too. Im curious if any wear will be seen with the chrome though over time. And I thought I saw some of the black stuff coming off already but Im not positive on that one.
