I'm really surprised to hear that you're still using the 17-35 after getting the 14-24. I suppose it could be sample variation but my 17-35 never impressed me at all and once I got the 14-24 that got multiplied by 50. I haven't touched it once since.
I also was never blown away by the 28-70. Although back when I owned it I didn't know about autofocus microadjustment, I'm now realizing...
The 14-24 is an excellent lens no doubt. For the mobile genres I usually work in I've always preferred to us 35mm still lenses with screw-on filters on Red One and now Epic. For lightness and mobility me and my crews don't use matte boxes or follow focus units. Unfortunately though I love the 14-24 optically, there is no way to put a screw-on filter on the front of the lens, and in what I feel is a mistake by Nikon there is also no way brackets on the rear of the lens so that gel filters could be used. My Nikon 14mm 2.8 has those rear brackets for gel filter use - but the 14-24 doesn't. I still use the 17-35 in the focal lengths that overlap the 14-24 (17mm to 24mm) so that I have the easy option to simply use screw-on filters.
The 28-70 has worked well for me on Red One as a mid-focal range interview lens. Its not a "world beater", but optically it generates quite pleasing results on Red One. It does not hold focus on a zoom, but I'm not worried about that - I use it as a variable prime anyway. The barrel telescoping when its zoomed isn't a problem for me because I simply use the lens with screw-on filters.
