Yes, I like the habotai silk and would use it again. I don't think it's for everyone, though. I used 5mm silk, and 8mm would probably be more appropriate for a longer lasting quilt. I especially like the silk when not wearing sleep clothes.
Although this quilt was used down to 25F, I also use it indoors in roughly 60 degree temperatures very comfortably, but when indoors I like to sleep just below the sweat point. If I do any trips in warmer temps next year, I may consider going with a 2.5osy XP, and I'll stick with the 5mm silk. It's cheap enough that if I do have a problem, I'll just cut off the damaged silk layer and replace it.
If you get a sample and sew it to some shell material, you'll see that you can pull it off the shell, but it is difficult to have a catastrophic failure. The website link I provided shows a photo with the start of a failure at the stitching in the silk. That was after 10 days in the field and a couple months directly on me in bed at home.
