omaplattas are always useful. if you dont get the sub, the sweeps that can come out of it are incredible. then you gain top position and regain a dominant position. thats my opinion. a lot ppl i kno that train say its useless and only works on noobs but the anxiety that graplers go through when their arm is caught allows them to make mistakes or give you the sweep.
