Michura is right, the flood route he just described can kill any zone unless your opponent way overplays the outside. The smash/divide is extremely good against all forms of cover 2, 2 sink will let you hit the hitch to the outside reciever. I perfer the Divide over smash because even though they both maintain the same hitch/corner the Divide gives you a deep threat in the middle to keep the deep coverage from being able to rotate down to the corner.
