The 18K carbon fiber face
The face is where spin and control live. The Primus runs an 18K carbon fiber weave — the same tight, high-thread-count surface the major brands put on their flagship paddles. It grips the ball longer through contact, so you get heavier spin on your drives and a more predictable pop on resets. This is the single spec most responsible for how a paddle feels in your hand, and it's identical to paddles selling for triple the price.
