Use a hook with an out turned eye such as a choddy and a knotless knot should be fine. The other option is to use the flouro in a combi link with a braid or to attach it with a palomar knot to any hook you want and to use a separate material for the hair. As for the comment that you need a fluoro hooklink or the fluoro mainline is a waste thats totally off the mark. I use fluoro as my mainline because it sinks like a brick and is great for slacklining, that has nothing to do with the hooklength material at all which in my case varies dependant on what bait, hook rig i'm using at the time.
