I have these on my current irons and I love how they feel. They are so silky smooth. I am curious if anyone else uses them or have tried them what their thoughts are about them. I would recommend them to anyone. My swing has slowed a little and the 105’s in regular hardstepped once just feel like they made them for me. If your still searching for The shaft for you try them at a Titleist Thursday or a fitting. I think you will be pleasantly surprised. Cheers,
