It's a shame the solo knit band seems to be form-over-function, it looks cool and a ton of work clearly went into developing it, but nearly everyone seems to find the much simpler dual loop band to be more practical.
e: I stand corrected, the reviewers I've watched mostly preferred the dual loop but there's plenty of solo knit fans here. I guess that YMMV factor is why they include both.

As the owner of a long head, I definitely struggled with feeling like I couldn't get the VP to sit right for my eyes with the solo loop. The dual resolved that easily.
Then you get to have the single loop as new fidget toy.
