The UST Mamiya Recoil Dart ESX is my first iron shaft review in 2025. Review samples came from a major brand that offers them as a small upcharge. An option well worth the investment if you are considering carbon fiber shafts in your irons. It has been a long time since I looked at UST Recoils. I had a relationship with UST when they introduced the idea that hoop deformation added to club head speed. Unfortunately at about that time I began documenting hoop deformation and could not see much difference between the recoil and other carbon fiber shafts. And certainly not any similarity to steel shafts. That is no longer the case. As you will see below, the hoop deformation profile of the recoil is unique.
