I am curious if anybody knows why this happened to me. I have been a long user of the Isometric head shape and one day I decide to bring my Carlton Airblade 350 to the club. Numerous times, when I went to do an overhead smash, I completely missed it. Just as simple as that, I just missed the bird. Does anyone know why that happened to me? Does it have anything to do with switching between head shapes? Again, it happened numerous times.
