WTB: Katabatic Palisade or Zpacks quilt

Looking for a light down quilt/hoodless bag for summer use in the high sierras - ideally good to about 30 degrees (with a light down jacket.)

I have a Katabatic Sawatch 15 degree which I love but I'm looking for something lighter for summer use - 16-19 ounces ideally.

I'm 6' tall with a slim build so I don't need a wide and the 6' length should be long enough.

Let me know what you have, thanks!
Allen
