Curious if anyone knows the "standard" swing weight of the T100S? I'm assuming D2? Mine came stock. Project X LZ 6.0, standard grips and length. Being that every shaft weighs 120g, does this mean the swing weight changes throughout the set? I assume since every shaft weighs the same, but aren't the same length, the head weight would have to change in order for swing weight to remain constant. I bought them off the shelf at a retail dealer and didn't think to ask at the time because they felt good. And still feel good. I love these irons. I'm just curious at this point. Entered them in the "product registration" on the website but shows no specs on them.
