Re: anyone have experience with an xx shaft?xx-stiff? No, but I have played x100 hardstepped 2x in my irons and x-stiff tipped about 3/8" in my woods. The x100's in my irons were great. They were like point and shoot. Very straight and very low trajectory. I really had to get after them though, x100's hardstepped 2x was honestly too much stiffness for my game. If my swing was off just a little, it showed up right away and wasn't pretty. I was a young kid though, I thought I needed shafts that stiff, at least that's what the guy at the golf shop said (I learned quickly to stop listening to those guys). The x-stiff shafts in my woods were alright too. Lots of control but the feel was off, they were boardy so I went to a softer shaft in those as well.
The truth of the matter is shafts that stiff really don't fit my swing. I have a faster swing speed (roughly 116mph) but I have smooth transition so I really fight to load shafts that stiff. How is your swing speed and transition? Do you need a shaft that stiff?
