Trying to find the perfect 20 degree quilt

Nunatak Arc UL 20 - 58" shoulder, 40" foot, differential cut, ETC, 15.3oz of down, 22.4oz total weight $448
Gryphon Gear Aries 20 - 54" shoulder, 36" foot, differential cut, ETC, 17.5oz of down, 24.25oz total weight $390 (really more of a 15 degree bag)
Enlightened Equipment Revelation 20 - 54" shoulder, zippered foot, 16.08oz of down, 22.54oz total weight $290
Feathered Friends Tanager CFL 20 - 62" shoulder, 38" foot, differential cut, 13.3oz of down, 19.7oz total weight $399 (Note: This is not a quilt and arguably shouldn't be included in this video. It's a very different tool. Quilts are optimized for comfort wheres the Tanager is optimized for efficiency)
Katabatic Gear Alsek 22 - 52" shoulder, 38" foot, differential cut, 13.4oz of down, 21.9oz total weight $420
With comfort and efficiency in mind, I really think the best option for me (with my 5'11" height and 160lb weight) might be a custom Nunatak Arc UL 15 with a 54" shoulder, 38" foot, differential cut, ETC, 17.6oz of down, 24.9oz total weight. That final weight might actually be a little less considering the smaller dimensions. The total cost would be $468. I'll post an article soon explaining why I have (maybe) landed here.
