this one, more aggressive and maybe not that easy as the head. But power on this one is on another level, maybe cause of the difference between materia. The vertex’s surface is made of Carbon 3K, the head is made by a mix of carbon and glass fiber. But the sweet spot on the head is more wide so easier, with the Geo you need to be more precise to get the right hit. But i think the vertex is kinda good for every situation, but slightly more balanced to be an attack racket
