I’ve tried all 3 shafts in various weights:
Steelfiber 95S. Hated it!
MMT 105TX. Liked, but not great!
Recoil 110 F4 Prototype was hands down best of the bunch for me! Dispersion was very good. Best launch numbers, an smooth feel
I was fitted at a local country club an Recoil wasn’t in the top 10 shafts recommended for my swing!
I went thru 3 sets of irons w the top 3 shafts, recommended at my fitting. None of them just felt right! An then reshafted an old set of irons w the Recoils! Winner! Winner! Cost me a few Grand to figure it out.
