The Adidas Rx Series 3.4 is a practical option if your priority is extra structural power and a more durable hitting surface without stepping up to a radically different frame. The carbon insertion and Smart Holes Linear arrangement combine to deliver a firmer, more driving feel that can add pace to your shots. For intermediates who value measurable power gains and a solid, long-lasting face, the Rx Series 3.4 is a sensible model to try.
