Eguller Just wondered. I bought the Sim Max irons with the Ventus shafts in them, A flex of course. Worst shaft ever, in my hands. Felt like the weight of straws, and far too flexy. That, plus the heads are about 8-11 g. lighter than what I refer to as 'normal'.....from a few years ago. Hope the shafts work for you.
I had the 2019 790's. Great looking heads(as are the 2021's) that performed as great as they looked. Had to send them along....my swing/game was not worthy of them in my bag. Very long hitting heads!
