ode Stiff, and not overly responsive. I have a set of the 125s that I have used for 4 years, they arenāt lively, but they are accurate, fairly low launch and they donāt spin a lot. I think most people would be better off in something else. Iām a high club head speed player, I have the S flex and have never been in danger of over flexing them. Most people are going to need more spin than these really want to give. Unless you are an outlier, I would not pay what they cost for a shaft that performs no better than the X-100, though doesnāt rattle your teeth with vibrations.
The wedge shaft is more neutral, but itās a wedge shaft. Itās not quite as stiff feeling, but again, you wonāt get a āloading and unloadingā feeling.
