The solution I came up with to that issue is to parent any prop, i.e. a sphere, to the head of your character, hide it, then load your strand hair without anything selected in the scene to avoid auto-fitting. Parent your hair to the prop (with parent in place turned off), then move and scale the prop to fit the hair to the skull. This is easiest if the hair has a separate skullcap, like FeSoul's hairs, so you can hide the strands while you adjust the fit. This will eliminate the wispiness, keep all the morphs intact, and you can add additional hairs by just adding them to the scene and parenting to the already adjusted prop. This also works for using G9 hairs on G8 (my primary reason for working this out) but you'll have to use a separate prop from native G8 hairs as they fit slightly differently.
But there's no comparison in the appearance of strand hairs - I've largely abandoned legacy hairs now that I have this workaround
