Wiring for recessed lighting through ceiling with floor trusses
I was waiting for our resident sparkies to chime in, but they're either busy or are also short on good answers. So...

I think that this situation is really no different from any fish job... think it through and don't yank. There are always hazards to your cable when fishing blind. If you find yourself pulling against a lot of friction, back up and start over. It definitely helps prevent friction and binding to have an assistant feed cable while you pull. 

I've pulled at least a few miles of cable, and the most damage I've seen from sheet metal gussets like those is a partial-thickness shave of the outer sheathing on the cable. I've had worse damage from pulling through wood stud bores around a corner. In the case of the gussets in that photo, all corners are over lumber, so it's unlikely that you'd get a full-grab puncture. 

So, yeah. Work carefully, pay attention, and hope for the best.
