The CFL might look bright, but it is nothing compared to your strobes. With that being the case, you won't want to try mixing the "continuous" CFL with the strobes. It will give you nothing but headaches.
You might try putting the 430 behind your subject and up as high as you can get it. As someone said before, dark hair on a dark background makes the subject blend in. With the 430 as a hair light, you can get separation from the background.
The continuous light might be of assistance in seeing the effects of light position on the subjects face, but other than that it isn't going to be much use.
