Adams Tech V4 Hybrid Graphite Adams Idea Tech V4 This new design has Velocity Slots in the crown and sole of the club, and also features a channel that is literally cut through the head of the club from the top slot to the bottom allowing for even more face deflection. It was important to seal the slots in order to be compliant with USGA regulations, so the Idea Tech V4 hybrids feature a TPU insert which also improves the feel and give the hybrids a very crisp sound similar to that of an iron.
