Agree w/ most of this.
However, and I couldn't believe this myself, but apparently Val weighs 135 lbs on fight night--and she says that's her walk around weight.
Weili weighed in at 127 lb (in cage) but claims to walk around at about 130 lbs. Meaning, Val's still bigger (plus I suspect she's a little leaner than Weili), but weight-wise, the size gap isn't as big as it seems.
That said, I still suspect that Val's upper body is functionally stronger (even if she couldn't outlift Weili in the gym). Not sure about their lower body though. That's probably Weili.
I also like the Val/Rose comp. However, Rose is a lot better on the ground than Val, by that I mean her BJJ skills, not necessarily "winning grappling and IQ." Rose's hands are also more threatening than Val's, even though I believe Val is the superior striker.
