So people have very different opinions on this. So in my experience:
Shutdown: seems to be one step on crack. A lotta times the db is glued to his target. And they go for the int all the time. I don't mean it's just pick artist. They often undercut the route to get the pick. Way more than without shutdown.
Universal coverage: I think this comes down to a weird phrasing in the description. In my experience it's all knockouts. Man and zone. Also faster reaction time from the zone knockouts. But not onestep. The thing is. Man knockouts don't have better reaction. Zone knockouts do.
What's your experience?
