Eguller iirc, I did have the R flex Ventus, at any rate, they only weighed 66g. , I came to find out. I pulled/sold them, and installed a set of Nippon Pro 1150GH, S flex....added the necessary weight where needed, and they were gold! But, far too nice for my game so I 'passed' them on before they got any marks on them.
I do still drool over pics of those irons though. 😄 But, the Apex 21s are also good lookers/players.
