With f/8 on a cloudy day you might get problem getting sharp image of the arms or have to settle on grainy image, regardless of the lens.
I would use fastest aperture I can that is still sharp and just shot a bunch of frames very quickly in hopes I can get arms in just the right, dramatic position.
As to whether to shoot wide or tele, if you feel you have enough time try to get subject to fill the frame first, while he still looks lively, and then quickly change the lens to get some additional shots with the background.
