No experience, but it sounds like it should keep you in shape. Maybe pre-drill the horizontals on the ground. They do make nail guns for monster nails--I think duofast makes one. But I'd see if you could toe screw boards down with GRKs or something. I use these suckers all time for flooring:

But if you're boards are wonky it's gonna be near impossible. And I'd plan on moving fast because if the boards get wet, they're gonna do weird things. Maybe tarp it at night. Any chance you could use 1x or 2x T&G with 1.125 plywood over it?
