I swear this is the first thing that anyone told me when I started climbing. I started with 4 which in most cases was enough, I was using extendable only when needed and using my sport draw for when I needed no extension. Or use the climbing What type of sling are we talking about and what type of belay loop? There has been at least one recorded case of a thin dyneema sling slicing a belay loop when a climber fell on it from max extension. The 8.
