I wouldn't think of going shorter than the standard ridgeline length of a HG 4S or Hex Cuben Fiber Tarp (10 ft. 10 inch or 130 inches).
Your Weight Weenie Micro is 11 ft. long (132 inches), and if your ridgeline is fixed at the traditional 83%, then that puts your hammock length at 109.56 inches. That leaves about 10 inches on each end for coverage.
Keep in mind that you'll have continuous loops or something through the channels that will add maybe 10 inches to the length of your hammock.
I have a BIAS DL and it's the same length as your WWM.
