if you're already taking the the 16-35, I'd probably say take the fisheye
I am more with that idea, i feel i want to do that circle fisheye, but maybe some prefer ultra amazing wide angle over circle fisheye.

But the 8mm fisheye is a very specialized tool. Not for everyone.
Ofcourse it is, full fisheye, i will shoot some urban and cityscape skylines, so to have full circle buidlings in the frame can be interesting, at least i will have a use for that lens since 2006.

If I were you, I'd just take them both out one day and run some tests. As you know they are VASTLY different in their framing, color rendition, and usefulness.
I own a Sigma 12-24mm EX DG and its one of my favorite lenses. But I have to say since adding the Tokina 11-16 f/2.8 to my bag, I find myself using the Siggy less and less, even on my only current FF backs (which are my film backs) being able to isolate subjects that are close in a deep scene @ f/2.8 all the way up to f/3.5 is well worth the trade-off for me versus 12mm on the Siggy. Thats not to say I would ever sell my 12-24mm because, simply put there is no equal to the 12mm look for when I want it. But if I'm happy with cropping out the vignetting in a shot, I am more than ready to shoot the Toki on film @ 12.5 mm f/2.8. I just find the f/4.5 limiting creatively as of late. And for full-frame sharpness on my 12-24, I found I need to stop down a click or two... so technically in my use its been closer to a f/5.6-8 lens than a f/4.5-5.6.
As for the Sigma 8mm f/3.5, I tried it and didn't like it. I compared it side-by-side with my Peleng 8mm f/3.5 and found the Peleng 8 sharper throughout much of the frame (with the Sigma winning at the extreme edges only) and easier to focus than the Sigma because of its DOF range markings. (I essentially manually focus the lens based on DOF and shoot @ f/4 or narrower).
I know all that, i just asked of what i have, and i can use both lenses ofcourse, but i don't want to carry 2, so i asked if someone has the option to choose only and only one, and i feel myself i want to go with fishy siggy for its circle effect which can be a fun sometimes in certain shots.
