Which Lens for Fashion - 24F1.4 / 35F1.4 for D800E

I use the Nikon 24-120 F4 95% of the time - mostly for studio work. My main problem is that even at minimum (1/32), my studio flashes still give too much light, so I cannot open the lens more that f8 for good bokeh. I've started using one dimmable LED light, works well but harder to control.
