Well look at ratio of orange hairs to non orange you want at least 50-70% orange to get that good high couch lock...if you can go by the tricohmes man but you need a magnifying glass at 60-100x or a jewels loupe at the same strength so you can see if there cloudy or milky or amber need that tool to better tell if your girls are getting close ..They look a little weird those girls but they seem like they should be good to flush soon they look about ready ...goodluck
