The main advantage of dual-pivot brakes is greater mechanical advantage (i.e. less hand strength needed). If you're accustomed to dual pivot brakes on other bikes, you may find single pivot brakes require disturbingly more effort to stop the bike. As others have noted above, braking from the hoods with single pivot brakes is more speed modulation than rapid stopping; for that, you go to the drops and grab the ends of the levers.
Chances are, you'd find a single, dual pivot front caliper to be sufficient to give the braking effort you expect. Campagnolo actually made their brakes that way: dual pivot front caliper, single pivot rear caliper. That reduces the risk locking up the rear wheel and going into a skid.
