I think I see what you mean. With the way the belt fits snuggly against my lumbar region after the last modification, I'm hoping that won't be necessary. However, if it is, I should be able to add a lumbar pad after the fact. The shape of the hip belt is an amalgam. I started with the G5 belt. The V came about initially from thinking about adding two separate darts to take in the slack, and then from reading about how the McHale hip belts form a V in both the front and the back. That's when I realized that adding a single dart in the back, or cutting off the extra altogether and reattaching it into the V shape is essentially the same thing.
