More IK-enabled long hair

Testing6790

I don't know what it's called exactly, but I have a few hair figures that have the strands / ponytail / length / whatever rigged to be select-able and moved with IK, which I am heavy user of. Ever since I got these few hairs it feels like I've lost some of my hair choices because all of the conforming long hair feels clunky.

A couple examples of hair that can do this is:
v4 twin braids (love that hair, so versatile)
Hitomi's non-curled hair

The ability to use IK on the back and the fringes save me so much time that I could buy them again and it'd still be worth it.
