I have the 6 point mount of the gamma 5003 at home and I have strung many before. If the machine has a 6 point mount system, do we have to use all 6 to lock the racket in place? Can I just use the 2 main ones instead? The reason I ask that question is sometimes, the side mounts get in the way of pulling strings through the holes near the mount which makes it annoying where I have to loosen the mount and tighten it back before pulling tension. Please advice.
