I'm a big guy, too. A little bigger than you. I have Ksyrium ES (same as SL) on my road bike, too.
As others have mentioned, I would have the wheels trued and tensioned first. That should be relatively cheap. Go to a good shop and ask for it to be done by the "go to guy" who knows his stuff. It costs the same and you'll be assured that the new guy isn't doing it.
