"The Adams Speedline Fast 12 fairway wood features Second Generation Velocity Slot Technology (VST). Second Generation VST – a slot within a slot – has helped engineers build upon the benefits found in the first generation of VST producing an 11% increase in CT over the Speedline Fast 11, and a 22% increase over fairway woods without a slot. This is because the new slot design in the Fast 12 fairway wood allows the clubface to compress more thus delivering higher ball speed + higher launch angle for dramatically longer carry distance and total distance.• Our longest and most forgiving ever! • VST 2.0 for even more ball speed, forgiveness and better launch conditions • Easy playability from all lies (both tee and ground) Draw & Standard Models. • New Grafalloy Pro Launch with Speed coat technology."
