At 10k miles they should be fine and they'll be pre-sagged for you. I'm guessing you know that OME springs always sag a bit after they've been on for a while. Not a big deal, but freaks some people out.
Whatever you do, make sure you get the coils you need for your application. If The 886s are the heavier coil recommended for the double cabs with a winch bumper. I'm running them on my accesscab and I like them so far; a bit stiff, but no sagging yet.
