Personally I love kinos, one nice thing is if you have them walking and singing into the camera the a 4x4 kino can easily be walked beside the camera and you well get a nice glow. Plus they aren't too heavy. Of course this depends on your ISO cuz a 4x4 may not cut it. They also make a nice fill light
One thing you must be careful of is not to make everything flat and bland because kinos do have a bit of throw.
