Sam gives a few pointers in this video on sidewall tension, why it is important and how to get yours tight. Creating a tighter sidewall eliminates margin of error and in turn increases consistency. Locking the mesh in place also greatly reduces the amount of wear on the sidewalls and the mesh because it reduces friction.
